Types of Level Transmitters Capacitance Level Transmitters Use the dielectric properties of the material to detect level changes. Ideal for liquids, slurries, and some solids. Hydrostatic Level Transmitters Measure liquid level by detecting the pressure exerted at a specific depth. Common in water treatment and storage tanks. Ultrasonic Level Transmitters Utilize sound waves to determine material levels by measuring the time of flight for an echo to return. Suitable for open tanks, wells, and even non-contact applications. Radar Level Transmitters Use microwave signals to accurately measure levels in both liquids and solids. Perform well in extreme conditions, such as high pressure or temperature. Magnetostrictive Level Transmitters Employ magnetic fields to detect liquid levels with high precision. Common in applications requiring tight measurement tolerances. Guided Wave Radar (GWR) Transmitters Transmit radar pulses along a probe for reliable readings even in challenging conditions like turbulence or foam. https://www.building-controls.com/product-type/test-and-measurement-instruments/level-transmitters
