Offshore kit has one job. Keep working. The Ajax XP ATEX electric flow switch from F. Bamford (Instruments) Ltd is built for exactly that, with a heavy-duty flameproof enclosure designed for potentially explosive atmospheres on oil and gas platforms.

Ajax instrumentation has been used on onshore and offshore petrochemical sites for over 70 years, mainly protecting cooling water and fire protection sprinkler systems. Every unit is manufactured in Stockport to ISO 9001. If you are specifying a flow switch for a hazardous area offshore, get the datasheet and talk to the people who actually build them.
