Level Transmitter Simulator – Interactive Level Measurement
Level can be found by pressure, buoyancy, weight, floats, electrical properties, sound, radar or radiation. Pick a level instrument, raise and lower the liquid in the tank, then change the fluid and the process conditions (foam, vapour, pressure, build-up) to find out where each type works well and where it fails.

Compare all level instruments
Explore how industrial level transmitters measure liquid levels using an interactive simulation. Compare sight glasses, magnetic floats, displacers, hydrostatic pressure, differential pressure (DP), capacitance probes, ultrasonic, radar, guided wave radar, and other level measurement technologies.
Adjust tank level, fluid type, foam, vapour, turbulence, tank pressure, and sensor build-up to understand how different process conditions affect measurement accuracy. Observe animated instrument operation, sensor signals, digital readings, transmitter output, measurement errors, and response curves.
This simulator helps instrumentation engineers, technicians, engineering students, and beginners understand level measurement principles, transmitter calibration, 4–20 mA signals, and instrument selection for industrial applications.
