Toshniwal Instruments Thermal Mass Flow Meters

Thermal Mass Flow Meters are used extensively by Industrial, Environmental and Commercial customers for Gas Flow applications. The innovative digitally-driven circuit eliminates the traditional drift-prone analog Wheatstone bridge utilized by competition. The reproducible zero flow data flow point enables the user to perform a simple single-point in-situ calibration verification procedure, which verifies that the flow meter continues to operate within the accuracy specifications of the original traceable calibration.
