4.3.5 Functional principle of diaphragm leakage
detection
Pumps with diaphragm leakage detection (MLS)
have a special dosing head flange for an
optoelectronic sensor. The pump is supplied with the
diaphragm leakage sensor (MLS) already installed.
The optoelectronic sensor contains:
• infrared transmitter
• infrared receiver.
Fig. 6 Diaphragm leakage sensor (MLS)
If the diaphragm leaks,
• the liquid enters the dosing head flange.
• the light refraction changes.
• the sensor emits a signal.
The electronics operates two contacts, which can be
used, for example, to trigger an alarm signal or to
switch off the pump.
4.3.6 Flow Monitor for dosing control
The pressure sensor (Flow Monitor pump option) is
used as a dosing controller and to monitor the
pressure for the whole power ranges.
The Flow Monitor for dosing control consists of a
pressure sensor integrated in the dosing head.
The pressure sensor is available as Flow Monitor
pump option. The pressure sensor is fitted to the
pump on delivery. Upgrades are not possible.
4.3.7 HV variant for liquids which are more
viscous than water
All HV-variant pumps are equipped with
spring-loaded valves, some have a larger nominal
diameter and adapters.
TM03 6216 4506
Note
Pressure control is primarily used to
protect the pump. This function is not
a substitute for the overflow valve.
Note
Note that the HV-variant pump has
other dimensions and that other
connection line dimensions might be
required!
