Non-Hazardous & Hazardous Area Flowmeters

Ultrasonic Flow Meters

Katronic’s KATflow 170 is an ATEX fixed flowmeter which utilises ultrasonic technology to measure the flow rate of liquids within pipes without entering the pipe within Zone 1 and Zone 2 hazardous areas. The KATflow 170 is designed to be suitable for harsh environmental conditions and provides a corrosion-resistant option as part of a fully ATEX certified package.

Fixed ATEX Flowmeters For Zone 1 & Zone 2 Hazardous Area Applications

Fixed ATEX Flowmeters For Zone 1 & Zone 2 Hazardous Area Applications

KATflow 170 ATEX flowmeters are suitable for pipe diameters ranging from 10mm up to 3,000mm and have a robust IP66 enclosure constructed from either epoxy-coated aluminium or stainless steel and has an LCD display and glass fronted keypad.

Stainless steel sensors, cables and connectors are supplied as standard for temperature ranges from -50ºC to +115ºC with higher temperature ranges on request. The KATflow 170 allows for the measurement of two flows simultaneously in explosive atmospheres and hazardous area locations.

Stainless Steel Flowmeters – atex certified

Katronic KATflow 170 flow meters with ATEX certification are available in both aluminium and corrosion resistant stainless steel for offshore installations where exposure to corrosive hydrocarbons and seawater atmosphere exists.

The minimum operating temperature of the Katronic KF170 is -20oC. For applications where the temperature levels are lower we recommend that the flow meter is installed inside a secondary housing to avoid any damage to the meters display.
