Operating Principle:
The Model 600-9/9500 operates using a constant temperature system that employs two RTD sensors: one for sensing temperature, and one for sensing flow. The flow sensor is heated to a precise temperature above that of the fluid passing by. The fluid conducts heat off the sensor in direct proportion to the mass flow rate. The temperature sensor is used to set the heat on the flow sensor and correct changes in the fluid temperature.
Thermal Instrument's thermal mass flowmeters consist of one piece; a flow element with a bridge controller, signal conditioner with power supply, flow signal, A/D converter, linearizing network, 4-20 MA DC, flow output, operational flow display, and totalizer.
