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 initial commissioning are met, see "First commissioning", page 26.
1. Disassemble and clean the flowmeter before recommissioning
- or -
► Heat up the liquid during standstill by means of a heating system, see "Heating system", page 9.
2. Switch on the system.
Under the requirements mentioned above, the flowmeter is ready for operation at any time.
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 capacity", page 12.
▪
The limit values shown in the following table must not be exceeded even for a short time.
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.
