R (Flow Transmitter) Series

The R Series offer the same versatility as the B Series meter with the addition of a digital or analogue output. Ideal for permanent installations where feedback is required to go back to the control PLC or where flows need to be data logged. These meters can be mounted in any orientation and come in a rugged cast Aluminium housing. Each meter has a 0-5V, 4-20 mA and frequency output allowing it to connect to virtually any system. With scales for water, oil and air/Nitrogen the R Series can be used in most industrial and process applications such as hydraulics, cooling water, air lines & compressors and Nitrogen blankets to name a few.
