Special types for high and low temperature operation (-10 ~220°C), Special (-45 ~400°C)
Available with integral limit switches & transmitters.
Installed for out of ground or under ground vessel.
Ability to install from side-side and top of the vessel. Fig A,B,C
Low cost.
Usable for interface process (double liquid).
The S-ch KM-20 liquid level indicating system is designed for use in applications where a simple gauge glass cannot be used. Due to its design the KM-20 can safety be used with flammable corrosive or toxic liquids or where operating condition exceed safety limits of glass. The rugged construction of the KM-20 make them ideally suited for use in operating environments where extreme temperature and/or pressure may encountered.
The basic KM-20 systems consist of a float, float chamber, indicator assembly and connection flanges or nipple. The float chamber is connected directly to the process vessel. The float contains a magnet assembly and is designed and weighed to float in the process liquid. A graduated scale corresponding to the desired operating range. The indicator assembly is mounted in close proximity to the float chamber. Magnetic coupling exist between the float and the indicator. As the float following changing liquid level. The indictor changes position to reflect that level due to the coupling action.
