The G sensors are mounted into a pipeline by means a standard G pipe outer thread (BSPP ISO 228 / DIN 259). These sensors are primarily designed for a modernisation of an existing installations, where an old mechanical water meters are still used. Its built-in lengths are based on a same ISO lengths as the water meters has. It means, that the replacing of an archaic water meter for a modern electromagnetic flow meter is really simple and quick. No any changes of an existing pipeline. Just replacing of the old one to new one.
The sensor covers could be made from a standard carbon steel with an epoxy painting finishing. Optionally it can be made from a stainless steel SS304 or SS316L, to meet hygienic requirements and requirements to operate in aggressive and humid environments. For operations with particularly aggressive influences (high relative humidity, acidic or alkaline environment, high / low temperatures, …), these sensors can be delivered in a separate design. In this case the transducer (flow meter display unit) is connected to the sensor with a shielded cable up to 40 m long, then it may be located outside of these areas. Separate sensor design can be optionally made with IP68 protection.
These “G” flow tubes are only made with PTFE (Teflon) liner, with a choice of several sensing electrode materials (316L stainless steel, Hastelloy C, titanium, tantalum,…).
These sensors can be used to measure the flow of drinking water, wine products, fruit juices, milk, whey, beer and other, too. The stainless sensors also resists cleaning lye and acids that are used daily in these industries. The PTFE liner and the flow meter itself meet hygienic requirements according to Act No. 258/200 Coll. and Decree of Ministry of Health No. 409/2005 Coll. to products coming into constant contact with drinking and hot water. The PTFE liner and SS316L electrodes complies with the EU regulation EC No 1935/2004.
