DIFFERENTIAL PRESSURE FLOW METER
The FurnaceMeter™ represents a full range of precision flow measurement instruments utilizing our proprietary differential pressure flow measurement design proven to meet the rugged requirements of industrial heat-treatment applications. The meters utilize precision, field-proven, and certifiable differential pressure flow measurement sensors. The advanced calibration and display modules on the electronic versions include integrated flow rate alarm and flow consumption totalizing functions.The FurnaceMeter™ meets current NFPA86 guidelines for safe usage in the thermal processing industry. In addition, every FurnaceMeter™ comes complete with a 10point calibration curve traceable to a NIST transfer standard. The meters can also be field calibrated to meet CQI-9, ISO, NADCAP and QS quality audit systems.
The FurnaceMeter™ is available for either gas or liquid flow measurement. These meters can also be fitted with integrated manual flow control valves specifically designed for the gas type, inlet pressures, and scale ranges to provide precision process control for most applications.
The FurnaceMeter™ provides a retrofit footprint to most variable area meters to minimize piping changed when upgrading to differential pressure technology and in-situ calibration capabilities.
