Product Summary
ThermoTrack
® Energy Flow Management System
The ThermoTrack Ultrasonic Transit Time Flow Management System is a non-invasive HVACR 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 suppliers to the outside of the pipe wall and the system is ready to measure. In addition, several units can be daisy-chained and wired into a single personal computer for a convenient central monitoring and billing system. ThermoTrack’s design is inexpensive to install; requiring no rebuilding, no system drainage, and no system downtime all resulting in measurable cost savings. Features: Suitable for conductive liquids Digital output to a PC for energy monitoring/billing of discrete units within a building PC communications (com) port supports a 3-wire network that can contain up to 128 discrete ThermoTrack energy units All meter components clamp to the outside of the pipe - no downtime for installation
CV Venturi
The CV Venturi Flow Meter is a differential pressure element designed to accurately measure the flow of liquids, gases or steam 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 easily be installed in any position with minimal straight pipe requirements (5 pipe diameters upstream and 2 pipe diameters downstream). Features: Accuracy of ±2% of readings uncalibrated
Repeatability of ±0.1% of readings Turndown ratio of 10:1 Low permanent pressure-loss design
Available in sizes 1/2" to 48"
Air Flow Measuring Station
Preso manufactures three air flow station models: AYR, SYR-RYR, and SYP-RYP. Preso's stations use the patented “Ellipse” elliptical shaped
flow sensors manufacturer.
Sensors manufacturer are available in multi-point averaging formats and complete duct section flow stations with averaging arrays. Models: AYR Model - insertion style sensor (rectangular or circular ducts)
SYR-RYR - ASHRAE averaging array (rectangular or circular ducts)SYP-RYP - ASHRAE averaging array (rectangular or circular ducts with built-in flow straighteners) Advantages and features include: Light weight Easy installation High accuracy Low cost
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 gage block across Venturis,
Pitot tubes, orifice plates, filters,
manufacturers of heat exchangers, etc. The GM & GMD gages come equipped with a large dial that features a 270° arc for fast and accurate readings. Features: Accuracy is ±1-3/4% Maximum line pressure is 500 psi Maximum overpressure is 60 psi
Maximum temperature is 180 °F GMD provides readout in flow units
