SpotCheck is a liquid level switch for use in applications where avoiding contact is vital. The sensor is clamped externally to the wall of the pipe or vessel. The method of measurement is suitable for steel, plastic or glass up to 50mm thick.

Working Principle

SpotCheck uses an ultrasonic “footprint” to determine the presence of absence of liquid inside a tank or pipe. It provides two wire, 24Vdc operation with an appropriate current sensor but also incorporates a relay switch output.

The piezo-electronic transducer emits ultrasonic energy into the wall of the tanks or pipe, which acts as a wave-guide. The electronics detect the difference between “wet”, “dry” and “fault” conditions.

In order to ensure that SpotCheck will operate satisfactorily, the surface of the tank or pipe must be prepared properly.

Typical Applications

Tank high / low level alarm
Non contact level switch
Overfill procedure
Pump run dry protection
Pig Detection
Tanker off-load pump control
Liquids with suspended solids and free gas
Detect liquid / foam interface
Aggressive or toxic liquids, effluent, sewage etc.
Hygienic level switch for hygienic liquids, foodstuffs, pharmaceuticals, chemicals
Flowing and static liquids
High or low pressure pipes or vessels
Detect presence of spray e.g. Tank washing
