Katronic KATflow 170 Hazardous Area Ultrasonic Flowmeter

Katronic KATflow 170 Hazardous Area Ultrasonic Flowmeter

The KATflow 170 provides a corrosion-resistant option as part of a fully ex-certified package for applications where harsh environmental conditions demand a more rugged instrument. The flowmeter is intended for permanent operation in Zone 1 and 2 hazardous areas and is an economical choice for a variety of metering applications. The KATflow 170 demonstrates that even the most complex technical requirements can be met with straightforward solutions.

The KATflow 170 flowmeter is designed around a choice of explosion-proof housings available in either offshore industry compliant epoxy-coated copper-free aluminium, or stainless steel. The instrument is extremely easy to use and is programmed with a magnetic pen and a glass-fronted keypad for increased safety. The robustness and reliability of the KATflow 170 is further enhanced by its encapsulated IP 68 transducers which are manufactured from stainless steel and have a sturdy cable conduit.
