Switching off the flowmeter
Operation
► Switch on the system.
The flowmeter measures when the pick up generates a signal.
Switching off the flowmeter
Safety instruction for switching off the flowmeter
Switching off the flowmeter
When the flow through the flowmeter is stopped, the generation of the signal stops automatically. No
further measures are required to switch off.
Recommissioning the flowmeter
Prerequisite:
□ The requirements for commissioning are met, see "Commissioning", page 32
1. Disassemble and clean the flowmeter before recommissioning
- or -
► Heat up the liquid during standstill by means of a heating system.
2. Switch on the system.
Under the requirements mentioned above, the flowmeter is ready for operation at any time.
CAUTION
Measuring error through gas inclusion in the pipe system.
► Before commissioning, make sure that the flowmeter is filled.
► Vent the pipe system.
CAUTION
Increased wear and/or blocking of the flowmeter due to solid particles or abrasive fine particles in the
liquid.
► Protect the flowmeter by a correspondingly dimensioned operating filter in the pipe system.
Pay attention to the following when switching off the flowmeter:
□ Strong changes to the flow rate (e.g. rapid shutdown, pulsations ...) cause marked pressure
differences on the flowmeter and can damage the measuring unit.
▪ The pressure loss of the flowmeter must not exceed the values given in the chapter "Technical
data", see "Load-bearing capacity", page 12.
CAUTION
Damage to device through hard, gummy or crystallized liquid in the flowmeter.
► Before commissioning, ensure that there is no hard, gummy or crystallized liquid in the flowmeter.
