Ultrasonic Sensors for Level Monitoring in Gravel Silos

Ultrasonic Sensors for Level Monitoring in Gravel Silos

Application Problem: Customer required level monitoring in very narrow tanks with welding joints on the walls, close mounting of the ultrasonic device to the wall (12 inches). Material in the tanks was gravel mixed with sand. Application History: Several contact and non-contact systems with ultrasonic included were tried. Unstable echoes (tanks’ walls, dust, shape of […]

Chemical Reactor Ultrasonic Level Measurement

Chemical Reactor Ultrasonic Level Measurement

Application Problem: Small chemical reactors with agitators and hot liquids. CIP (Clean In Place) is used for 30 min. The customer needs 1.5 inch tri-clamp sanitary sensor that is very reliable in level measurement and does not need to be removed during CIP. Application History: Capacitance and also ultrasonic sensors were used with limited success.

Wastewater Channel Radar Level Measurement, radar level transmitter

Wastewater Channel Radar Level Measurement

Application Problem: A wastewater treatment plant required a level sensor that could reliably measure with ice on liquid. Application History: No other brands of level sensors were able to eliminate ice influence and measure liquid surface. Solution: ABM’s non-contact radar level sensor was used to eliminate the influence of ice on the surface and provide
