Digital Flow Meter

Compact, lightweight direct reading Flow Meter for measurement of flow for a gas selected from multiple options.

Accurate flow measurement is of fundamental importance in Gas Chromatography, air pollution sampling, gas metering and other industrial applications. Wrong flow measurements can lead to misleading results in respect of concentration of air pollutants, which in turn could result in health risks and / or wasted man hours. Accurate and quick periodic calibration of flow measuring devices like rotameters and flow generating devices like sampling pumps is an important requirement.

Polltech’s Digital Flow Meters afford accurate and fast flow measurements in air sampling applications.

Available Models:

Panel Mountable Type : PSI-DFM 1 PM-L, PSI-DFM 1 PM-M, PSI-DFM 1 PM-H

Hand Held Type : PSI-DFM 1 HH-L, PSI-DFM 1 HH-M, PSI-DFM 1 HH-H

Physical Design Highlights

Digital Flow Meter is designed to measure flow by measuring the differential pressure across an orifice. The pressure in turn is measured by a solid state pressure sensor. The orifice, the pressure sensor, the flow connections and the electronics are all housed in a single cabinet. The electronics is a microprocessor based unit which performs the tasks of interfacing with sensors, timing, computations and operator interface. The unit has a provision for G.C. users to select any of the gases i.e. Air, O2, N2, H2, He, Ar / CH4 and CO2. The flow is automatically corrected for the properties of the gas. All instruments are provided calibrated reports with traceability to National standard.
