One of the oldest and most common methods of measuring liquid level is to measure the pressure exerted by a column (or head) of liquid in the vessel. We offer solutions with submersible sensors and through the tank wall sensor options.
The 400 series of submersible pressure transmitters includes a number of completely submersible pressure-sensing transmitter models ranging from 0 to 1m water column to 0 to 500m, that contain an air vent tube for providing a pressure differential relationship between the hydrostatic head and the atmosphere. The transducer contains associated electronic circuitry for providing an analogue output, has an IP 68 protection rating, and requires a 24 Vdc ± 10% Power Supply One of the regular applications for these transmitters is tank level monitoring & control.
Ultrasonic sensors provide a cost effective sensing method with unique properties not possessed by other sensing technologies. By using a wide variety of ultrasonic transducers and several different frequency ranges, an ultrasonic sensor can be designed to solve many application problems that are cost prohibitive or simply cannot be solved by other sensors. Ultrasonic sensors continuously emit high frequency sound pulses inaudible to the human ear which travel away from the sensor, hit the surface of the target and are reflected back to the sensor. The sensor electronics measure the time taken by the signals to return after being reflected by the target surface.
Since the speed of sound is affected by air temperature, our ultrasonic sensors include a built-in temperature sensor. Level/distance measurements are automatically temperature compensated throughout the operating temperature range of the sensor.
Classic applications include proximity sensing, object presence or absence, obstacle detection for automated vehicles, distance measuring, level measuring, etc.

[…] Level switch ini bisa bekerja pada media liquid normal seperti untuk water level, untuk oil seperti fuel level atau oil level atau solar level, namun ada juga yang bekerja untuk matrial not liquid seperti powder, biji-bijian atau lumpur. Jenis dari liquid yang mungkin bersifat korosif atau yang lainnya akan menentukan jenis material untuk floating switchnya. Jenis Level switch yang paling banyak digunakan adalah jenis float level switch baik untuk oil maupun air. Untuk jenis float level switch solar menggunakan material float dari stainless steel sedangkan untuk float level switch yang diaplikasikan di air banyak menggunakan jenis non logam. […]
