LPR Wireless Transmitter

Designed for on-line corrosion monitoring of water systems in electrically hazardous areas. Instantaneous corrosion rate measurements are made using linear polarization resistance (LPR) measurement technology.  

The most common use of the transmitter is for corrosion rate and pitting tendency in water systems.  However with a set galvanic electrode, the transmitter may be operated in a galvanic monitor mode, which is particularly useful in high pressure water injection systems for detection of low levels of oxygen in the parts per billion range (ppb), where conventional dissolved oxygen meters cannot be used.


LPR Wireless Transmitters and other Cosasco Wireless devices come standard either with ISA100 Wireless or WirelessHART 7 communications protocol to seamlessly integrate into virtually any wireless process system including Yokogawa (ISA100) and Emerson (WirelessHART 7).
