Using a newer laminar differential pressure flow technology, these mass flow meters and controllers have a much lower pressure drop across the instrument. Meters and controllers require no warm-up time, and offer a 10 ms response time for meters and 100 ms for controllers. Typical applications include air sampling, natural gas metering and calibration, and gas analysis and totalizing.
Select from 30 different gases in real time with the gas and gas mix calibrations already programmed into the meter or controller. An integrated keypad around the display is all that is required to program the unit for service. The 0 to 5 VDC output permits transmission of the flow value to a remote display, recorder, or controller regulating a valve or pump.
Battery-powered meters allow you to take the meter from site to site for flow rate establishment and on-site calibration. They have a monochrome display and rechargeable integrated battery packs.
Voltage-powered meters and controllers feature a color backlight TFT (thin-film transistor) display and are designed for single-area use. The TFT display allows you to see when the meter or controller is at max range or out of range; each numeric reading of the four parameters (mass flow, volumetric flow, pressure, and temperature) change to yellow at 100% of range and red at 128% of range.
