CTA Series Heavy Duty Hydraulic System Flow Monitor CTA150-MA-S-6 | FT11429-03

Description & Features

The WEBTEC CTA Series Heavy Duty Hydraulic System Flow Monitor, model CTA150-MA-S-6, excels in demanding environments, providing accurate flow and temperature data for machinery. It supports a flow range of 5 to 150 L/min (1.3 to 40 US gpm) and withstands pressures up to 420 bar (6000 psi). With a fluid temperature range of -40 to 85 °C (-40 to 185 °F), it is compatible with mineral oils conforming to ISO 11158, and other fluids upon request. The robust aluminum body ensures durability, while the steel and stainless steel internals add reliability.

This flow monitor features a 1-1/16"-12UN #12 SAE ORB porting and an M12 5-Pin Code A electrical connection, operating efficiently on a 9–28 V DC power supply. Rated at IP6K9K, it is well-protected against dust and high-pressure water jets, making it ideal for harsh conditions. Lightweight at just 1.1 kg, it provides ease of installation without sacrificing performance.

rated for outdoor equipment or just shop use? we run these on skid steers and the machines sit outside year round, get rained on pretty hard sometimes

IP6K9K is about as tough as it gets for water ingress protection. That rating covers high-pressure washdowns, not just rain, so outdoor exposure on skid steers shouldn't be a problem from a sealing standpoint. The fluid temperature range runs from -40 to 85 °C, so cold-weather starts in winter are covered too. FKM and EPDM seals hold up well against the kind of mineral oils typically running through that equipment.
