EMCO by-pass chamber is connected to the side of the vessel applying the principle of communicating vessels. The chamber acts as a stilling well. EMCO by-pass chambers are used with electronic level transmitters based on GWR (Guided Wave Radar), conductance, capacitance or displacer principle for protection against turbulent and agitated liquids. This product is compatible with the Siemens SITRANS LG240/ LG250/ LG260/ LG270 Radar Transmitters
