GENERAL DESCRIPTION


The DVZ series vortex flowmeters are the perfect solution for applications where reliability and low cost are desired. The DVZ senses the flowrate of low viscosity liquids using the vortex shedding principle. A small obstruction called a bluff body is placed in the flowpath. As fluid flows across the bluff body, a small low-pressure area called a vortices is created just behind the bluff body. The position of the vortices alternates to either side of the bluff body in a uniform pattern. The frequency of the vortices shift is directly proportional to flowrate. This shift in the vortices is detected by a very sensitive pressure sensor and processed as a flowrate signal.

DVZ - Vortex Flowmeter and Switch

The vortex flowmeter has no moving parts and thus is very reliable. The DVZ series is available with a Ryton body and a choice of either nickel plated brass or 316 stainless steel fittings. The bluff body is available in either ryton or ceramic, which has excellent long term wear characteristics.

The available outputs are frequency, 4-20 mA, adjustable relay, and compact electronics with digital flowrate display, 4-20 mA output and adjustable transistor switch options. The device series is rounded off by an optionally available batching or totalizing electronic.

 Areas of Application

  • Monitoring the flow of low viscosity liquids
  • Measuring of aggressive, high-purity, or salty solutions
  • Not suitable for abrasive media or media containing a large proportion of f bers
