The patented HVT-Halmi Venturi Flow Element designed, developed, and perfected by Dezsoe Halmi, founder of Primary Flow Signal (PFS), is offered exclusively by the company for the highest accuracy and reliability for flow measurement of pressurized line fluids, including liquids, gases, and steam, as well as high-viscosity line fluids, solids-bearing line fluids, and harsh or contaminated line ...
Leopold ® Simplex LPL Venturi Flow Element. The Leopold ® Simplex LPL venturi flow element is ideally suited for accurate flow measurement of almost all liquids and gasses including liquids with suspended solids, gasses with entrained liquids, chemical solutions, slurries, steam, and air.
A Venturi meter is a flow measurement device, commonly utilized in the water supply industry. A Venturi meter specifically uses a converging section of pipe to increase flow velocity. A corresponding reduction in pressure permits a determination of the flow rate. The Venturi meter is based on the Venturi effect.

The orifice, nozzle and venturi flow rate meters use the Bernoulli Equation to calculate fluid flow rate using pressure difference through obstructions in the flow . Sponsored Links . In a flow metering device based on the Bernoulli Equation the downstream pressure after an obstruction will be lower than the upstream pressure before. To ...

Department of Mechanical Engineering Venturi Meter ... A schematic of the Venturi meter is shown on the diagram at the end of the procedure. The inlet diameter equals d – 26 mm and the throat diameter d = 16 mm. The pressure along the meter is obtained using the 11 pressure taps at the locations shown on the diagram. The water flow rate can ...
A venturi meter with a 3 in. diameter throat is installed in a 6 in. pipe-line. The pressure at the entrance to the meter is gauge and it is undesirable that the pressure should at any point, fall below absolute. Assuming that for the meter is 0.96, find the maximum flow for which it may be used.
Venturi meters are flow measurement instruments which use a converging section of pipe to give an increase in the flow velocity and a corresponding pressure drop from which the flowrate can be deduced. They have been in common use for many years, especially in the water supply industry.
The raw water is metered through a 42-in. venturi meter and the flow rate is controlled with a 30-in. sleeve valve. The primary oxidant, chlorine dioxide (ClO 2) dosed at 0.3 to 0.5 mg/l, is injected immediately downstream of the sleeve valve. The ClO 2 is primarily added for
Venturi Flowmeters . The differential producing flowmeter or Venturi has a long history of uses in many applications. Due to its simplicity and dependability, the Venturi is among the most common flowmeters. With no moving parts or abrupt flow restrictions, the Venturi can measure fluid flowrates with a minimal total pressure loss.
