Compress Air Thermal Mass Flow Meter CS VA 525 Cs Instrument

 

CS Instrument Thermal Mass Flow Meter

 In-Line Air Flowmeter Model VA 525

The newly developed VA 525 combines modern digital interfaces for connection to an energy monitoring system with a small, compact design. Due to its reasonable price and modern digital interfaces this compact in-line flow sensor is used when many machines (compressed air consumers) are to be integrated as easily as possible into an energy monitoring network.

Feature

• Compact, small design - for use in machines, behind maintenance unit at the end-user
• Optionally with classic analog signals(4...20 mA and pulse) or digital interfaces such as Modbus RTU, Ethernet (also PoE), M-Bus
• All interfaces are programmable via the display
• Current consumption in m³/h, l/min,...
• Total consumption (meter reading) in m³, l, kg
• Temperature measurement
• Optional: pressure measurement
• Easy installation in existing piping through integrated measuring block (suitable for 1/4 ̋, 1/2“, 3/4 ̋, 1“, 1 ¼ ̋, 1 ½“ or 2" lines)
• Display values can be rotated 180° in the display, e. g. when installing overhead
