Cole-Parmer’s newest laminar differential-pressure flow technology is designed for a much lower pressure drop across the instrument. The technology has been added to the company’s Low Pressure Drop Flowmeters and Controllers for Gases. Full-scale pressure drops are as low as 0.1 PSID to 0.69 PSID, and the meters measure 30 standard gases with a 200-to-1 turndown ratio. Typical applications using this functionality include air sampling, natural gas metering and calibration, and gas analysis and totalizing. The meters and controllers are designed to require no warm-up time and offer a 10 millisecond response time for meters and 100 millisecond for controllers. The new technology allows you to choose from 30 different gases in real time from the gas and gas mix calibrations already programmed into the meter or controller. An integrated keypad can be used to program the unit for service.
