The UDM-20 float level (interface) transmitter can continuously measure the liquid level or interface (when measuring the interface, the density difference between the two liquids is ≥ 0.1g/cm3). It is matched with the HF series digital display alarm and can be used for remote measurement, adjustment, control, and alarm of liquid level and interface in departments such as petroleum, chemical, textile, food, brewing, pharmaceuticals, ships, power generation, and water supply and drainage. This instrument is a two-wire instrument with an output current of 4~20mA.DC and a power supply voltage of 24V. DC.
