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
