The latest addition to the range of Flo-Dar open-channel flowmeter is an ATEX certified portable system with built-in GPRS Internet data transfer facility (photo). This new model enables the entire system to be mounted in the zoned area, with nothing above ground, and provides operators with a range of features and benefits. For example, unlike conventional sensors, it does not require weekly maintenance visits; it has a rechargeable lithium battery that can be recharged in hazardous areas; operators have no contact with the flow during installation; no profiling is required; and it has field-interchangeable sensors and monitors. The system is certified to ATEX Zone 1, works in surge conditions. It is suitable for all pipes and channels from 100 mm upwards. — Flowline Ltd., Borehamwood, U.K.
