Series 400 ValuMass™ Flowmeters
Low Cost / High Value
Our ValuMass™ Series 400 offer another lower cost option for many flow applications with the high value associated with all of EPI’s flow measurement instrumentation.
ValuMass™ flowmeters include a robust feature set: 0 – 5, 10 VDC, 4 – 20mA, RS485 Modbus RTU and optional 0 – 1 kHz outputs (proportional to the gas mass flow rate); an RS232C port; 16-bit linearization technology for flow rate accuracy; a fully programmable relay; and rugged construction of 316/316L stainless steel wetted parts. An optional 2-line, 16-character backlit LCD displays the flow rate and the elapsed total readouts.
ValuMass™ inline and insertion flowmeters accommodate virtually all installation requirements. The Series 400 inline style flowmeters are available for line sizes from ¼” to 2”. The 3 ½” long flow sections have MNPT ends as standard for easy mounting in the process line. Other end fittings are available. ValuMass™ flowmeters accept 24VDC, 115VAC or 230VAC input power as specified at the time of purchase.
