Level
Sensors
The
PVL level sensors range includes capacitance probes and liquid
level switches, level sensors and fuel gauges, conductivity
probes and controllers with a wide range of specifications,
depth pressure and sludge level transmitters, vibrating fork
and optical level sensors and high temperature and pressure
sensors working at up to 500 bar and 400ºC. PVL can supply
you with sensors for water, oil, coolant, fuel and most corrosive
liquids or hostile environments, electrically damped sensors
capable of dealing with turbulence, capacitance probes and
controllers for tanks up to 3 metres deep - in fact just about
everything you will ever need for sensing fluid levels.

MODEL 28PU |
HYDROSTATIC TANK CONTENTS GAUGE |
|

|
The 28PU gauge uses the hydrostatic principle of proven reliability and simplicity and requires no power supply. This method requires minimum installation time and gives important advantages in the safe measurement of volatile liquids.
By operating a small hand pump, fixed at the bottom of the gauge, charges the system with air under pressure. The liquid is displaced from the balance chamber at thebottom of the tank, while excess air escapes via the tanks vent.
The resulting pressure in the balance chamber is indicated by the gauge and is proportionate to the head of liquid in the tank.

MODEL 28PUE |
HYDROSTATIC TANK CONTENTS GAUGE |
|

|
The 28PUE gauge uses the hydrostatic principle of proven reliability and simplicity, with push to read electric pump using 4 AA batteries or mains power supply via plug in 6v adaptor.
This method requires minimum installation time and gives important advantages in the safe measurement of volatile liquids.
The resulting pressure in the balance chamber is indicated by the gauge and is proportionate to the head of liquid in the tank. The gauge can be mounted at any position, and may be disconnected at any time without upsetting the calibration.

MODEL 38 |
BATTERY OPERATED LIQUID LEVEL GAUGE |
|

|
The Model 38 gauge uses the hydrostatic principle of proven reliability and simplicity, with a push to read electric pump using 4 AA batteries.
The gauge unit can be mounted in any position and may be disconnected at any time without upsetting the calibration. Maintenance is not normally required, except battery replacement, as there no moving parts external to the gauge unit.
