Remote Tank Content Gauge
The Baysend and Minisend gauges are
simple float operated devices fitted with
precision potentiometers to enable remote
monitoring. A separate power unit is
provided to measure the rotation of the
potentiometer and transmit a scalable
voltage or current signal to a remote indicator
or data acquisition / control system. The local
dial may be calibrated in Fractions,
Percentage, Litres, m3 or any other standard
engineering units. Dial sizes available are 50,
100, 150 and 250 mm diameter depending on
gauge type. Versions for hazardous areas
are available.
Operation
As the liquid level in the tank changes the float arm moves vertically through an arc. This displacement is
transferred via gears to a rotating drive magnet located in a pocket behind the gauge mounting flange. A
second magnet located inside the gauge body follows the drive magnet, rotating the potentiometer shaft and
pointer. This mechanism prevents fluid leakage into the gauge and allows adjustment or maintenance to be
carried out without the need to drain the tank. End of travel float arm stops are fitted to ensure that the float
does not come into contact with the inside of the tank.
Up to 2 micro switches can be fitted onto the same shaft as the potentiometer to provide integral level alarms.
Remote alarm and pump control modules are also available to provide adjustable multi-level control facility.
The Minisend gauge is fitted with the B9 size mounting flange and the Baysend with either the B15 or B23
depending on tank depth. Other flange types are available on request.
Please see separate data sheets for details of remote indicators and control units.
