Ultrasonic Flowmeter EESIFLO PORTALOK 7SZ


For the past 15 years, EESIFLO® http://www.eesiflo.com has helped thousands of plant operators, engineers and technicians successfully measure the flow of all possible fluids through every type of pipe from 1/2 inch to 100 inches in diameter, without cutting into their pipes or shutting down their processes. The term "downtime" is not part of our vocabulary.

Our battery operated Portalok ultrasonic clamp-on flow meters are currently being used in every corner in the world, in hundreds of diverse applications. We have seen your application many times in the past, and our Portalok will solve your flow measurement problems immediately.
