Mass Flow Meter has tiltable LCD.
Press Release Summary:
Self-contained Model GFM thermal mass flow meter measures gas flow up to 100 sL/min with accuracy of ±1.5% and repeatability of ±0.5% f.s. Flow rate is unaffected by temperature and pressure variations. Output is 0-5 Vdc or optional 4-20 mA. Response time is typically 2 sec. Maximum pressure is 500 psi. LCD readout provides readings in direct engineering units in terms of specific gases. Aluminum and stainless steel models are available.Original Press Release:
Low Cost Mass Flowmeters
The enhanced model GFM is a low cost self-contained Thermal Mass Flowmeter, designed to accurately measure the flowrates of gases.
A tiltable LCD readout is built into the top of the meter. Readings are in direct engineering units in terms of specific gases. Remote reading installations are possible by means of an optional extension wire supplied with a modular phone plug.
A nine pin "D" connector is included to facilitate 0 - 5 Vdc and 4 - 20 mA analog outputs.
Flowrates are unaffected by temperature and pressure variations.
Aluminum and stainless steel models are offered. Zero and span adjustments are conveniently accessible from the outside, a dip switch is added for external adjustment of decimal point of the LCD readout.
Optional rechargeable battery kit is available for portability.
Accuracy: ± 1.5% of full scale.
Repeatability: ± 0.5% of full scale.
Maximum Flow: 100 sL/min [N2].
