New PVC filter monitors from Orange Research measure differential pressure to check the health of filter media in filtration equipment for water and corrosive liquids. The lower cost, smaller size monitors can save hundreds of dollars over the life of a system by indicating the optimum time to clean or replace filters. Savings can be even greater when major components are at risk.

The easy-to-read dial models have benefits not offered by two pressure gauges. The single dial simplifies training, installation and maintenance while reducing operator errors. Reduced size and cost offer an effective filter optimization solution.

Popular in water treatment systems, the filter monitors are available with 1” or 2.5” diameter durable plastic dial cases. Switches are standard options to alert users of alarm conditions. Transmitter and switch versions are available on request. The PVC bodies and wetted parts improve compatibility and assure long service life. The bodies are rated at up to 150 psi line pressure and are conveniently small sized, measuring
1” D x 1.5” H x 1.5” W.

Precision made piston sensors handle differential pressure ranges from 0-10 to 0-30 psid, covering most filter monitoring applications. Accuracy is 5% full scale and each unit is calibrated to NIST (National Institute of Standards and Technology) standards.

PVC filter monitors come standard with 1/8” female NPT process ports on the bottom of the body. C-clamps are available to mate units to panels.
