SpotCheck from HMA INSTRUMENATTION 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 50 mm thick. SpotCheck is easy to install and set-up. Simply push the calibrate button when the sensor is uncovered. A red/green/amber LED gives an indication of status.

The Series 1000 SpotCheck from HMA INSTRUMENATION is powered by 24 V dc, and includes a single relay output for wet or dry indication. SpotCheck uses an ultrasonic footprint to determine the presence or absence of liquid inside a tank or pipe. 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.

Applications include 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 solid and free gas, detecting liquid/foam interface, aggressive or toxic liquids, effluent, sewage etc., hygienic level switch for hygienic liquids, foodstuffs, pharmaceuticals and chemicals, flowing and static liquids, high- or low-pressure pipes or vessels, and detecting the presence of spray, for example tank washing.
