The extraordinary reliability of the KOBOLD paddle-type PPS flow switch is available at a competitive price and can be installed in pipes 1” and larger. These units, made of polysulfone, are virtually maintenance free. The pressure drop across the instrument is negligible and independent of the pipe diameter. Switch status is clearly visible through the polysulfone housing. The PPS is available with either a normally open or a normally closed contact. Installation is easy. Simply insert the PPS in a standard T, or a reducing T, sealed with teflon tape. Allow for a straight pipe of at least 3-times the pipe diameter on either side of the T to avoid turbulence.
