A vent air flow meter is commonly used in many industrial applications when gases and air are vented and there is a need for environmental compliance or energy conservation. Thermal mass meters offer an effective method to measure air and gas flow.

Industrial Venting Applications

Air and gases are vented in various industrial situations in which air and gas flow measurement may be required. These situations can include supply air, exhaust air, flue gas in incineration, vent air for environmental compliance, exhaust flow in stacks, test pumps for leaks, air flow to heat treating furnaces and drying air.

The turndown and sensitivity of thermal mass flow meters provide an excellent solution for measuring various types of air and gases in industrial applications. Furthermore, the thermal mass flow meter provides direct mass flow (no need for separate temperature and pressure instrumentation), has ease-of-installation and negligible pressure drop, all of which beneficial to air flow applications.

Air Flow Meter

The Sage Prime Thermal Mass Meters have extraordinary rangeability of at least 100 to 1, as well as fast response. Furthermore, the Sage air flow meters are digitally driven, resulting in extreme low-end sensitivity (as low as 5 SFPM), and extraordinary reproducibility. Sage Meters have 4 – 20 mA outputs of flow rate, pulsed outputs of consumption, in conjunction with fully Modbus compliant RS485 RTU communications. The meters also feature bright graphical displays of flow rate, a non- resettable totalizer (often a requirement for environmental reporting), a temperature reading, plus, continuous diagnostics. For difficult to reach pipes, or for locations with extreme radiant heat, Sage also offers a remote style flow meter, with up to 1000 feet of lead length compensated cable – all electronics and powering are done at the transmitter – thus, the probe simply has a terminal junction box.
