商品説明

The FMA1700 and FMA1800 series has been discontinued. Please see the upgraded FMA1700A and 1800A Series as a possible alternative or contact our Flow Engineering Department.

The FMA1700/1800 Series electronic gas mass flowmeters provide for monitoring the flow of a wide variety of gases from 10 SCCM up to 1000 SLM. Utilizing heat transfer through a heated tube to measure molecular gas flow rate, the FMA1700/1800 provides measurement of direct gas mass flow rate, without the need to compensate for variations in gas temperature or pressure (within stated limits). They are available in an economical aluminum/brass construction for typical gas flows and a 316SS construction for applications requiring more corrosion resistance. The FMA1700 series without integral display is supplied with a field selectable analog 0 to 5 Vdc or 4 to 20 mA output for remote monitoring; the FMA1800 series has both an integral 3½ digit display and analog output. The display is tiltable over 90° for viewing convenience. The display is calibrated standard to read out directly in SCCM or SLM for nitrogen (other gas calibrations available on special order).

Due to their low cost, digital display, analog output capability, and insensitivity to variations in gas temperature and pressure, the FMA1700/1800 Series are ideal substitutes for many variable area flow meter applications. When used with the FMA178BP portable battery pack, the FMA1800 Series are ideal for in-the-field calibration of flowmeters or testing of air sampling equipment. The FMA178BP battery pack includes batteries, recharger, and carrying case with shoulder strap and belt loop. With the FMA178BP, the flowmeter can operate in excess of 40 hours; the batteries can be recharged at least 200 times.

The FMA1700/1800 Series require 12 Vdc power @ 200 mA maximum, which can be supplied by the FMA178PW plug-in socket power supply. The electronics are reverse polarity protected and has externally accessible fusing. Model number FMA178C (supplied separately) provides a mating 9-pin “D” connector with 3 feet of ribbon cable for accessing the 0 to 5 Vdc output signal and power input connections (use FMA178C-MA for 4 to 20 mA output signal connection).

The LCD supplied with the FMA1800 Series is connected to the lower electronics via a modular plug. The LCD can be remotely located by purchasing an FMA18RC remote cable assembly-you must then build your own assembly for panel mounting the LCD.

Flow ranges specified are for nitrogen or air at 20 psig. When used for other gases, a multiplication factor is used to determine the flow rate, and the digital display must be rescaled in the field. Or request a custom calibration by adding the gas and pressures as a suffix to the model number. All calibrations done at ambient (20C/70F) temperature only.

FMA1700/1800 Transducers should not be used for monitoring Oxygen Gas unless specifically cleaned and prepared for such application. See below for ordering instructions.
