Endress+Hauser PROMAG 33, Operating Manual

Page: 11 / 126

Installation of pumps
Do not mount the sensors on the
suction side of pumps. This prevents
low pressure and therefore possible
damage to the lining of the measuring
tube.
Information on the resistance to vacuum
of the flowmeter lining can be found on
page 115.
Pulse dampers should be installed
when using reciprocal, diaphragm or
peristaltic pumps.
Vibration
The piping before and after the sensor
should be securely fastened if there
is excessive vibration.
Information on shock and vibration
resistance is found on page 110.
Caution!
Excessive vibration necessitates
separate mounting of the sensor and
transmitter (see pages 20, 109).
Mechanical support of the sensor is
recommended for free runs of piping
over 10 m long.
Caution!
