DXN Hybrid Flow Meter

The DXN Ultrasonic Hybrid Portable Flow Meter

The DXN can measure the flow of pure liquids as well as liquids with entrained solids or aeration. The transmitter will switch between transit time and Doppler measurements on the fly based on the condition of the media inside the pipe.

At Derex, Inc. our entire rental fleet consists of DXN flowmeters. Our rental units experience a wide variety of applications and conditions and the DXN has proven itself to be reliable, rugged, accurate and maintenance-free.

This unit can measure: Flow Rate, Temperature in Liquid.

  • Vortex
  • Variable Area
  • Mass Flow

Ultrasonic flowmeters are able to measure a wide variety of industrialgases and superheated steam independent of temperature, density andpressure influences.

Krohne has been the leading manufacturer of Ultrasonic flowmeters and world leader for in-line measurement devices for more than 25 years. The meters can be used in bi-directional metering with great accuracy and long-term stability. They can also be used in a wide range of pressures and temperatures.

Since 1943 DFT® Inc. has manufactured world class, problem solving, inline, axial flow, nozzle style silent check valves and severe service control valves.

DFT® silent check valves are known around the world as the valve to use to prevent or eliminate water hammer problems. We specialize in providing in-line check valves that meet customer requirements as opposed to simply meeting line size. In some cases, minor modifications to our valves have solved customer problems by improving performance and extending service life.
