VA 40 WIM variable are flow meter

Product News Tuesday, February 10, 2015: KROHNE Pty Ltd

With the new option "WIM" ,a 4...20mA electrical output signal is now available for the variable area flowmeter VA40. While the flow rate with these glass devices could previously be read only locally, the new option allows for transmission of the measured value for control or evaluation purposes.

With VA40 WIM version ,the height of the float is converted into an electrical signal via a Hall sensor chain. This signal can be used for PLC/DCS,or to record the measured value over a certain periodwith a dat logger. Along with each VA40 WIM, KROHNE supplies the calibration curve, allowing the customer to assign the exact flow value to any current value.

VA40 variable area flowmeter are used for the volume flow measurement of liquids and gases. e glass measuring tube enables visual inspection of the medium to evaluate properties such as gas entraintmets or colouring. Typical applications include measurement of flushing,purging or inerting gases, heating and colling circuits, gas measurement in industrial furnaces ,or other basic applications in machine building and process industries ,where this purely mechanical pronciple has proven itself for almost 100 years.

All connection variants of the VA40 are aso available with the WIM option. With the robust stainless steel taps, the maintenance-free device is mounted directly into the pipeline using flange, screw ,clamp or hose connections.An installation in hazardus areas according to ATEX II2G Ex IIC T6 Gb and ATEX II2D Ex ia IIIC T85⁰C Db is possible. Retrofitting the WIM option to existing devices is not possibe.
