Flow Measurement
Primary Flow Elements
QPS Orifice Plates
Quality Products & Sales manufactures Paddle, Universal and RTJ style orifice plates in virtually any material. All plates are inspected in a controlled environment to ensure that the bores meet or exceed AGA and ISA specifications.
QPS Averaging Pitot Tubes
High Pressure Hot Tap. This sensor can be installed under high pressure without shutting down the system. We have corrected the common problem of the single nut tightening, by using the heavy duty tie rods systems of tightening the packing gland. No extra tools needed. The Stainless Steel tie rods assure easy insertion or retraction.
QPS Classical Venturi
Quality Products & Sales manufactures two types of Classical Venturis Fabricated from Carbon Steel, Stainless Steel and Brass. The short form Venturi has a 15° diffuser cone. The long form venturis has a 7° diffuser cone aiding in pressure recovery.
QPS Wedge Meter
QPS Wedge meters are custom designed to handle all types of liquid, gas & steam flow applications; Slurries High Solid Contents Corrosive Erosive Features: Sturdy one-piece construction Low permanent pressure loss Extended range of pipe sizes, schedules and connections Chemical seals available for hazardous application Benefits: Time tested, reliable technology Designed for Bi-directional flows Accurate measurement of low reynolds number flows No moving parts, therefor less maintenance and inspection
QPS Integral Orifice Assembly
Integral orifice assemblies are ideal for pipe sizes under 2" NPS. Since the assembly is designed to direct mount to any standard transmitter or manifold, there is no need for fittings, tubing, vlaves or adapters. Over 50% of the possibilities for leaks and headaches are eliminated. All these advantages add up to a very accurate, simple and affordable metering device.
