  1. Preso Air Flow Pitot Tube

    Preso Air Flow Pitot Tube

    The AYR Ellipse Air Flow Measuring Sensors are available for single or multiple installations in round, square or rectangular ducts. Constructed of anodized aluminum with two independent fl ow sensing chambers, these sensors are designed to prevent signal degradation and mixing. The unique patented elliptical design provides high accuracy and repeatability with low permanent pressure loss.
  2. Preso B-Plus Balance Flow Control

    Preso B-Plus Balance Flow Control

    The B-Plus Balancing Valve features Preso's "Low-Loss" Venturi design, unsurpassed in the industry for low permanent pressure loss and low energy consumption. The B-Plus is accurate to ±2% and installs in any position with minimum upstream and downstream piping requirements. The B-Plus is available in 15 sizes from 1/2" (12.7mm) to 10" (254mm) with sweat, FNPT, flanged and grooved-end connections. Many options are available: pressure and temperature ports, quick-disconnect fittings, readout gages and transmitters.
  3. Preso BAR Ellipse® Pitot Tube

    Preso BAR Ellipse® Pitot Tube

    The Ellipse Pitot tube flow meter is a primary flow sensor designed to produce a differential pressure that is proportional to flow. Its patented elliptical shape provides the lowest pressure loss in the industry. The Ellipse flow meter is designed with a series of ports facing the upstream velocity pressures and flow sensing ports strategically located ahead of the trailing edge flow separation. As a result of this innovative design, the Ellipse is capable of highly accurate, precise flow measurements that are proportional to the actual flow rate to 24 inch Pitot tube meter for liquids and gases.
  4. Preso BHR Ellipse Wet-Tap Pitot Tube

    Preso BHR Ellipse Wet-Tap Pitot Tube

    The Preso Ellipse annular flow devices are primary flow sensors designed to produce a differential pressure that is proportional to flow. Its elliptical shape provides the lowest pressure loss in the industry. The Ellipse flow meter is designed with a series of ports facing the upstream velocity pressures and flow sensing ports strategically located ahead of the trailing edge flow separation. As a result of this innovative design, the Ellipse is capable of highly accurate, precise flow measurements that are proportional to the actual flow rate.
  5. Preso BIN Annular Pitot Tube

    Preso BIN Annular Pitot Tube

    The BIN is a highly reliable averaging pitot tube which generates a pressure differential between its upstream (stagnation) ports and its downstream (static) ports that is proportional to the fl ow rate squared. It can be used to measure liquid or air in pipe sizes between 2" and 24". An opposite support is supplied standard on pipe sizes 8" and larger.
  6. Preso CV Venturi Flow Meter

    Preso CV Venturi Flow Meter

    The CV Venturi Flow Meter is a differential pressure element de signed to accurately measure the flow of liquids and gases by forcing the flow into a smaller diameter section of pipe, then measuring the pressure differences between the unrestricted flow and the restricted flow. It can be installed in any position with minimal straight pipe requirements (5 pipe diameters upstream and 2 pipe diameters downstream).
  7. Preso Ellipse Model BHL

    Preso Ellipse Model BHL

    The Preso Ellipse annular flow devices are primary flow sensors designed to produce a differential pressure that is proportional to flow. Its elliptical shape provides the lowest pressure loss in the industry. The Ellipse flow meter is designed with a series of ports facing the upstream velocity pressures and flow sensing ports strategically located ahead of the trailing edge flow separation. As a result of this innovative design, the Ellipse is capable of highly accurate, precise flow measurements that are proportional to the actual flow rate.
  8. Preso GM & GMD Differential Pressure Gages

    Preso GM & GMD Differential Pressure Gages

    Preso GM & GMD gages accurately measure differential pressure between two points. Offered in a variety of mounting configurations such as flush panel, pipe and surface mount or select a portable kit for field applications. Both the lightweight GM portable kit and the GMD Direct-Readout Meter are suitable for differential pressure measurement across Venturis, Pitot tubes, orifice plates, filters, heat exchangers, etc. The GM & GMD gages come equipped with a large dial that features a 270° arc for fast and accurate readings.
  9. Preso ThermoTrack® Energy Flow Management System

    Preso ThermoTrack® Energy Flow Management System

    The ThermoTrack Ultrasonic Transit Time Flow Management System is a non-invasive HVAC energy flow monitoring solution for commercial and industrial buildings. ThermoTrack is built on a non-invasive platform, as a result all system components clamp to the outside of existing pipe, making it ideal for retrofit applications. Simply strap the flow and temperature transducers to the outside of the pipe wall and the system is ready to measure.
