Test
Procedure
Installation
► Check the installation position of the flowmeter
with regard to the flow direction.
► Check the installation and installation position
of the pick ups and of the temperature sensor.
► Check the pipe threading/flange and the
temperature sensors for leaks under operating
pressure.
Electrical installation
► Observe the corresponding operating
instructions for pick ups, temperature sensors
and electronic equipment.
Power supply
► Observe the corresponding operating
instructions for pick ups, temperature sensors
and electronic equipment.
CAUTION
Measuring error through gas inclusion in the pipe system.
► Before commissioning, make sure that the flowmeter is filled.
► Deaerate 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.
