Eldridge Products, Inc. (EPI) produces a wide variety of thermal gas mass flow meters and switches for measurement and control. Built with over eighteen years experience in thermal mass flow metering design and production, our thermal flow meters and flow switches have earned a reputation for superior quality, dependability, ease of use, and durability in real world applications. Our Master-Touch™ Family of thermal mass flow meters continues and greatly expands upon this legacy by adding a powerful microprocessor to our proven thermal technology for an unparalleled degree of flexibility, accuracy, and control.
 Eldridge Products, Inc.’s innovative new Flow Averaging Tubes (FAT) provide accurate flow measurement in large pipes and ducts without the expense and complexity of traditional multipoint systems, offering a cost-effective solution for Heating, Ventilation, and Air Conditioning (HVAC) and Variable Air Volume (VAV) applications.

CALORIMETRIC (THERMAL DISPERSION)
Weber Sensors
CoolGuard This is a unique product, in that it is a low priced solid state device and can compete price wise with mechanical switches and others. The unit also alarms if temperature is exceeded so it is two sensors in one. It is simple to install and requires no adjustments.

MODIFIED VENTURI / FLUME
Back to Top |

  |
 The DataGator combines a modified venturi flow tube design with strategically positioned pressure transducers to accurately and reliably measure flow under all conditions - including transitional periods between open channel and full pipe.
The flow measurement is derived from proven hydraulic theories using three distinct pressure readings within the pre-calibrated flow tube. By translating pressure directly into flow, the DataGator eliminates errors introduced by level and velocity conversions and average velocity calculations.
The DataGator's flow tube, available in sizes to fit 8", 10", 12", 15", 18", 24" , 27", 36"and custom size sewer pipe, is securely sealed to the pipe wall using an inflatable ring assembly. Housed in a submersible NEMA6P enclosure, the DataGator electronics are designed to withstand the harsh sewer environment.

 The Magnum Flowmeter is installed on any given pipe through a 2" tap. The tap consists of a welded 2" nipple, a short threadolet and a 2" NPT full bore gate or preferably ball-valve. The overall length of this tap assembly from the outside of the pipe to the end of the valve should not exceed 8 inches on pipes up to 50" diameter. If it is less then 6 inches a standard Magnum can be used on pipe sizes up to 70" diameter. Supply voltage 12-24V DC
Power consumption
6 Watt
0.5 Amp
A 12V car battery would drive the flowmeter for about 20 hours of continuos operation
Output signals
4-20mA, RS 232/485 (digital), Pulse; (+ and - flow)
Local indicator
128x128 graphic, flow, velocity, trend, total
Memory
Magio 2.0 (DOS) 2000 sample, volatile, adjustable flow recording
Magio 3.0 (WIN9X) none or 20000 sample nonvolatile (optional datalogger)
Enclosure Rating NEMA 4X
