This simple to install, all-in-one unit is fully assembled and factory calibrated for easy installation. They provide proportional analog or pulse outputs that will drive popular data acquisition devices, meters, and analog input cards. In addition to the transmitted flow data, the transmitter also provides visual flow levels on the local scale. The weather tight NEMA 4x cast aluminum enclosure allows for installation outdoors and where liquid-tight seals are required.
