Description PL301 Submersible level transmitter
The submersible hydrostatic level transmitter PL301 has been
designed for continuous liquid level monitoring in water wells,
reservoirs, tanks, boreholes, rivers and other liquids.
The submersible unit measures the static pressure of the liquid
column above the transmitter and transmits a current signal
proportional to the water column to the instrumentation above.
The highly stable 316L stainless steel diaphragm sensor is fully
compatible to raw or chlorinated water and most semi-aggressive
liquids.
Supplied with a special vented cable to compensate the atmospheric
pressure changes, it accurately transmits the measured liquid
level. The application-dependent cable length can be defined at the
time of purchase to the desired extent and can also be customer
adapted at the application site.
The PL301 submersible level transmitter / hydrostatic level sensor
is designed for use in rivers, reservoirs, tanks, boreholes,
vessels and channels. Thanks to their long term immersion
protection to 100 metres, they are also ideal for the measurement
of pressure within submerged pipes and vessels.For applications
where aggressive media such as seawater or leachate are present,
especially landfill sites, we can provide a high grade duplex
stainless steel submersible level transmitter with very high
corrosion resistance.
