System description

The UFM 400… and UFM 500… ultrasonic flowmeters are precision instruments designed for linear flow measurement of fluids.

The full scale range can be set (factory setting for UFM 400…) between 0.9 and 450 000 m3 per hour or between 3.9 and 1987 200 US gallons per minute, dependent on the meter size DN 25 through 3000 / 1” to 120”. This corresponds to a flow velocity of 0.5 to 18 m/s, which is equivalent to 1.6 to 59 ft/sec.

Lined drained. Faulty measurements

Horizontal and slightly ascending pipelines Always install signal converter (and terminal box) on the top or underside of the pipe,

10. Zero setting is normally not necessary, but it can be checked under flowing conditions as outlined in sect 7.2. Shutoff valves should therefore be provided upstream and/or downstream of the primary head unless the pipe configuration already rules out the possibility of the primary head being drained of fluid. (For zero check see section 7.2).

11. Mixing different fluid products. Install the flowmeter upstream of mixing point or at an adequate distance downstream, minimum distance 30x DN (DN = meter size), otherwise output/display may be unsteady.

12. Ambient temperature:

product temperature ≤ 60 °C/140°F

all systems: -25 to +60°C/ -13 to +140°F product temperature > 60 °C/140 °F

compact systems: -25 to +40 °C/ -13 to +104 °F separate systems: -25 to +60 °C/ -13 to +140 °F

13. Pipeline along a wall: where possible, the distance between pipe centerline and wall must be more than 0.5 m (1.6 ft) for the UFM 400 K and UFM 500 K flowmeters. If less, first connect all cables to the terminals in the terminal compartment (power supply and outputs), and install an intermediate connection box before installing flowmeter in pipeline.

14. Insulated pipeline: do not insulate UFM 400 K and UFM 500 K compact flowmeters.

15. Suggestions for installation

To avoid measuring errors due to air inclusion, please observe the following:

Part A System installation and start-up

1. Installation in the pipeline

1.1 Preliminary information

1.Location and position as required, but sensor axis must be approximately horizontal if flowmeter is installed in slightly ascending or horizontal pipe runs.

2.Hard-to-reach locations

Sensor axis (2 beams)

Sensor axis (1 beam)

Where UFM 400 K and UFM 500 K compact flowmeters have not been ordered and supplied in accordance with Versions 1 to 10 (see sect. 8.6), the configuration can be changed subsequently:

∙Turn the indicating circuit board through ± 90° or 180° to obtain horizontal positioning of the display (see sect. 8.4)

∙Turn signal converter housing through ± 90° (see sect. 8.5)

3.Measuring tube must be completely filled at all times.

4.Flow direction +/-: note arrows on flowmeter and also fct. 3.1.7 (refer to sections 4.3 and 5.4).

5.Bolts and nuts: to install make sure there is sufficient room next to the pipe flanges.

6.Vibration: support the pipeline on both sides of the flowmeter.

7.Large meter sizes, DN>200 (8”): use adapter pipes to permit axial shifting of counter flanges to facilitate installation.

1.3 Grounding

Warning

Instrument should be properly grounded to avoid personnel shock hazard!

1.3.1 Standard grounding

The flowmeter must normally be grounded via the protective conductor PE incorporated in the power supply cable. Connect the protective conductor to the separate U-clamp terminal in the terminal compartment of the signal converter. See sect. 2.1.2 for the compact flowmeters, and sect. 2.2.2 for the separate systems.

1.3.2Grounding with measuring ground M

This type of grounding must be employed if at least one of the two following operating conditions occurs:

A If large potential differences occur between protective ground and electric furnaces or electrolysis plants.

BIf a protective ground conductor is not provided, e.g. for DC voltage operation.

Observe the following when grounding with separate measuring ground M:

Do not connect up the protective ground conductor PE in the terminal box if measuring ground M is connected.

If the AC supply voltage exceeds 50 Vrms, then the measuring ground simultaneously acts as the protective

ground conductor (combined protective/functional ground). Refer to appropriate national codes for specific requirements for this type of installation, which may require the addition of a ground fault detection circuit interrupter.

1.3.3 Grounding in hazardous areas

Special regulations are applicable, refer to sect. 6.1, and the special “Ex” installation instructions.

1.4 Pipes with cathodic protection

·Pipes with electric corrosion protection are generally insulated inside and outside so that the fluid has no conductive connection to ground. The primary head must be insulated from the pipe. Note the following when installing the flowmeter:

·The pipe flanges must be connected to each other using a copper cable (L), but must not be connected to the primary head.

F100%	≤ 1.0 Hz	500 ms

If F100% > 10 Hz and ≤ 1000 Hz, the pulse-width duty cycle is 50%.

2.3.4 Status output S

∙The status output is galvanically insulated from the current output if the status output is used passively. Furthermore the status output is galvanically insulated from all other circuits except for the status output with which it shares a common (ground).

∙All functions and operating data can be set, see sect. 5.9 (not applicable to UFC 400… signal converter).

∙Factory-set data and functions are listed in the enclosed report on settings. This can also be used to record any changes made to the operating parameters.

∙Active status output, for electromechanical indicators or for electronic indicators, voltage between 19 to 32 VDC. Note that the total current for the active frequency/pulse and status outputs together (drawn from I+) may not exceed 50 mA. (see connection diagram 3 below).

∙Passive status output, open collector output for connection of electronic indicators, input voltage ≤ 32 VDC / ≤ 24 VAC, load current max. 150 mA.

∙Connection diagrams, see below.

3. (Initial) Start-up

∙Check that the system has been correctly installed as described in sect. 1 and 2.

∙With separate systems, check before initial start-up that the following details on the primary head nameplate agree with the data specified in the report of settings for the signal converter. If not, new setting will be necessary:

Order No., see instrument nameplates Meter size (DN), fct. 3.1.5, sect. 5.3 Primary constant GK, fct. 3.1.6, sect. 5.16 Flow direction, fct. 3.1.7, sect. 5.4

∙Before every start-up it is advisable to carry out a zero check if the flow can be zeroed, as described in sect. 7.2.

∙When powered, the signal converter operates in the measuring mode. TEST, NO ERROR and IDENT NO.

_ _ _ _ _ _ _ of the signal converter appear in succession in the display. This is followed by display of the actual flowrate and/or the internal count on a continuous or alternating basis (depends on setting, see report on settings)

4.2 KROHNE operator control concept

4.2.1 Description

The operator control concept for the UFC 500… signal converter consists of 3 levels (horizontal), see below.

Setting level:	This level is subdivided into 3 main menus.
	Fct. 1.0 OPERATION: This menu contains only the most important parameters and functions of
	menu 3 to allow rapid changes to be made during the measuring mode.
	Fct. 2.0 TEST: Test menu for checking the signal converter.
	Fct. 3.0 INSTALL.: All flow measurementand flowmeter-specific parameters and functions can be
	set in this menu.
Parameter check	Fct. 4.0 PARAM.ERROR: This level is not selectable. After exiting from the “setting level”, the
level:	signal converter checks new data for plausibility (inconsistency). If an error is established, the signal
	converter reverts to menu 4. In this menu, all functions can be scanned and those, that are
	inconsistent, changed.
Reset/acknowledge This menu has two tasks and is selected via Entry Code 2 ( −→), see sect. 4.2.5
level:	1) Separate resetting of totalizers, provided that resetting is enabled by setting “YES” under fct.
	3.6.10 ENABL.RESET.

2) Error scanning and acknowledgment (Quit)

Errors that have occurred since the last acknowledgment are indicated in a list. After acknowledgment and elimination of the cause(s), these errors are deleted from the list.

Function of the keys in the 3 levels

Cursor	Is the flashing part of the display. This can be a digit, a text, a unit or a sign.
→	The cursor key shifts the cursor to a new (different) position in the display. For the menu columns (see

	diagram in sect. 4.2.2) this means: transfer to the next “right” column, i.e. from left or right, up to the data
	column. Only in the data column parameters can be changed and functions can be initiated.
−	The select key changes the contents (digit, text) of the flashing cursor.
	— Digit	Increase value by “1”.
		(With fct. _ _ _, display next main or submenu or next function).
	— Text/unit: Display (select) next text/unit from a list.
	— Sign:	Change from “+” to “-“ or, with exponents, from “E” to “E-”, and vice versa.
	The accept key (return key) is used for:
	— acceptance of new parameters,
	— acknowledgment of displayed error messages in the reset/ackn. Menu, and
	— execution of displayed functions.
	For the menu columns (see diagram in sect. 4.2.2) this means: transfer to the next “left” column, i.e. from
	right to left, up to the main menu column. Only from the main menu column it is possible to exit the 3
	levels and return to the measuring mode.
Important	∙ If numerical values are set, which are outside the permissible input range, the display will flash after the
	“Accept” key has been pressed.
	1st line: permissible minimum or maximum value displayed.
	2nd line: TOO LOW or TOO HIGH.
	The incorrect numerical value is displayed again after pressing the key; set correct numerical value.
	∙ Time-out function: if the signal converter is in the setting level and if no key-strokes are set for approx. 15 minutes, the
	signal converter will automatically revert to the measuring mode without accepting any previously changed data.

To terminate

Keep pressing until menu fct. 1.0 OPERATION, fct. 2.0 TEST, or fct. 3.0 INSTALL. is

					S TO RE	YES

Storing the new parameters

Acknowledge with , display shows: “PARAM.CHECK”.

When no errors occur, the measuring mode will continue with the new parameters.

In case of an error, the display will show: “Fct. 4.0 PARAM.ERROR”. In this menu all functions that are inconsistent can be scanned. For this turn to sect. 4.2.2 and 4.3.

Do not store new parameters

Press the− key, display shows “STORE NO”. After pressing the key the measuring mode will continue with the “old” parameters.
