Operation

The MOBREY Squing is a two-wire device and may be installed in any position in a pipe or vessel to detect the presence of a liquid.

Squing has a turning fork style wetside which vibrates at its natural frequency when in air. A piezoelectric crystal system is used to create the oscillation. When the fork is covered by liquid, this frequency changes and is detected by the electronics which change the output state of Squing.

Standard two-core cable is used to connect Squing in series with the load. The solid state output stage acts as a simple SPST switch, operated by liquid presence. Squing may also be interfaced directly to a PLC using a third PLC terminal on the circuit board.

Application

Squing has a status indicated LED which can be seen at all times through a lens in the end cover. The LED will flash approximately once per second when Squing is "off" and will be constantly lit when Squing is "on".

The LED gives an indication that Squing is functioning correctly and of course gives a visual indication of the state of the wetside. A 'mode' switch on the circuit board is provided for the user to select either Squing on when dry - the normal condition - or on when wet, as would be selected for low level duties.

The fact that Squing is vibrating normally when dry makes it ideal for use in high-level detection applications. Any change in frequency, however caused, will turn Squing off an alarm may be activated. When included in a fail-safe circuit, Squing provides an extra degree of fail-safe improving system integrity.
