Zone 2 Flow Switch

February 21 2012 model fs10a flow switch monitor from fluid components international fci has received atex and iecex approvals.

Zone 2 flow switch. A complete line of liquid mcdonnell miller flow switches has been br developed for a wide range of. That is the reason for and the function of mcdonnell miller flow switches. At half the height of standard insertion flow switches these are often installed in tees or pipe outlets in low clearance areas. Flow switch monitor receives zone 2 atex iecex approvals fs10a from fci is optimized for continuous flow verification in process analyzer sampling systems.

However in a zone 1 area an insertion sensor may be fitted to a water or other non hazardous media pipe. Flow switch in zone 1 sensor may be inserted into zone 0 atex category ii 2g ex zone 0 instruction leaflet. In such a case a flow sensor for zone 1 insertion is appropriate. The flow of liquids in pipelines plays an important role in industry and commerce.

Our rugged electronic switch detects flow by monitoring the vibration generated by the rig mud pumps. Applications include proof of boiler flow air conditioning controlling of dampers according to flow and protecting pumps motors and other equipment against low or no flow. Under most circumstances it is essential to know whether or not there is a flow in a pipeline and to act upon that knowledge. Paddle flow switches or vane sensors with an electrical contact output are at a specific flow rate.

Flow switch a functional test should be carried out every quarter. Flow switch tester shall consist of a recirculating pump operating at nominal 110v or 220v as appropriate two 2 sets of valves and elbows to facilitate the circulation of the water a system sensor vane type water flow detector and a key switch to activate the recirculating pump. Flow switch designed to replace legacy electronic flow switches or operate as a standalone module. Switches are single pole double throw spdt and can be installed to.

Monitor flow in 1 2 to 2 12 70 to 50 80 mm pipe explosion proof compact flotect mini size flow switches are compact and designed to monitor liquid gas or air flows. It is fully compatible with tensor and aps platforms and uses a 3 axis vibration sensor to accurately determine flow conditions. They activate or deactivate equipment when the flow rate reaches your set point. Dwyer flow switches are economical and reliable.

The switches control dampers according to flow and shuts down burners when air flow through heating coil fails. With atex and iecex approvals the fs10a flow switch monitor is suitable for continuous flow verification applications supporting process analyzer sampling systems operating in hazardous plant areas in the european community and elsewhere worldwide. Zonecheck can carry out this flow switch test tories underwriters laboratories canada. Outside pipe zone 1 inside pipe zone 0.
