10 Operation

10.3 Decommissioning

10.2.2

Checking the function

1.

Check the flow direction of the flowmeter.

2.

Check the installation and installation position of the pick up and of the temperature sensor.

3.

Check leaks at the pipe thread/connecting flange.

4.

Check the electrical installation. Observe the operating instructions for pick up and electronic unit.

5.

Check the power supply. Observe the operating instructions for pick up and electronic unit.

10.2.3

Commissioning the flowmeter

ATTENTION

Increased wear and/or blockade through solid particles or abrasive fine particles in the liquid.

► Protect the flowmeter through correspondingly dimensioned operating filters in the pipe system.

ATTENTION

Measuring error when the pressure drops below the minimum pressure outlet at the outlet.

► Ensure that sufficient counter-pressure exists at the outlet by routing the piping upwards.

ATTENTION

Measuring error through gas inclusion in the pipe system.

► Before commissioning, make sure that the flowmeter is filled.

► Vent the pipe system.

Requirement:

ü

The ambient conditions correspond to the operating data

ü

Flowmeter installed correctly in the pipe system

Ä

Installation, removal, Page 23

ü

Flowmeter connection to the pipe system is stress-free

ü

Pipe system is free of impurities

ü

Pipe system vented

ü

Shut-off devices in the feed line and outlet opened

Switch on the measuring system.

ð

The flowmeter measures when the pick up generates a signal.

10.3 Decommissioning

10.3.1

Switching off the flowmeter

ATTENTION

Damage to the measuring unit.

In the case of strong changes to the flow rate (for example, rapid shutdown, pulsations, etc.) there is a
danger of excessive pressure differences.

► Ensure that the pressure loss of the flowmeter does not exceed the values specified on the rating

plate or the substitute operating data.

Ensure that the pressure loss of the flowmeter does not exceed the values specified on the rating

plate or the standardized substitute operating data

Technical data, Page 8.

ð

When the flow through the flowmeter is stopped, the generation of the signal stops automatically.
No further measures are required to switch off.
