Differential Pressure Flowmeters

Elliptical Throat Flowmeter Model SDR11F

Model No.
SDR11F
SDR

This flowmeter can measure a wide variety of fluids including liquids, slurry, gases, steam, solid-gas two phase flow containing powders, etc.

  • Elliptical throat structure for smooth flow
  • A large pressuer tap prevents clogging, so it can be used for various fluids.
  • Can be mounted directly on a remote seal transmitter.

Smooth flow

The constriction has a half-elliptical shape whose front and rear sections are smooth and streamlined, with nothing to impede the flow. The result is highly accurate and stable output with high repeatability.

Low pressure loss

Pressure loss is approximately 8 to 50 % of the generated differential pressure, which is smaller (1/2 to 1/4 at the same throttling ratio) than that of an orifice. Accordingly the flowmeter loses little energy, allowing the use of a smaller power source.

Quick response

This flowmeter is highly responsive, which allows follow-up even when the fluid is pulsating (up to 1 Hz).

Compatible with wide a range of fluids

The pressure inlet has a larger diameter (10–14 mm) than the standard orifice. Due to this large diameter, which does not cause clogging, the flowmeter delivers stable measurement even with fluid containing adhesives or solid substances. Use in combination with 1/2B remote transmitter provides instrumentation without a connecting tube.
