New ValueMass Flowmeter Designs for 2014
Press release date: June 6, 2014
The new ValuMass™ Models 490 and 590 insertion flowmeters from Eldridge Products, Inc. combine the economy of the ValuMass™ electronics with the innovation of the patented Flow Averaging Tube™ (FAT™) design.
The digital ValuMass™ electronics include a variety of output formats including 0–5 VDC / 4–20mA analog flow signals, RS485 Modbus RTU communications and a 0–1 kHz frequency output. The Model 490 has a compact aluminum enclosure for general purpose locations; the Model 590 has a robust enclosure approved for use in hazardous locations. Either model is available with remote electronics, if preferred, to accommodate virtually all installation requirements.
Similar in outward appearance to an averaging pitot tube, the FAT™ design provides accurate readings in large ducts by sampling the gas stream across the full pipe diameter — but the flow sensor is temperature compensated and insensitive to pressure changes. Therefore, the output signal is a true mass flow rate signal which can be directly interfaced with a data acquisition system without the need for additional temperature and pressure corrections.
