Catalog excerpts

Model 510C Mass Flow Meter aerospace climate control electromechanical filtration fluid & gas handling hydraulics pneumatics process control sealing & shielding Porter Model 510C Series II Mass Flow Meter is designed for precise measurement of virtually all conventional process gases. The 510C consists of a thermal mass flow sensor, and microprocessor based circuitry with signal and fieldbus conversion. The mass flow rate is provided as analog signal or digitally via RS232 or various fieldbus options. Each unit is specifically sized and calibrated depending on the type of gas and the process conditions of the application. Product Features: • Full Scale Flow Ranges from 0.7 ml/min to 9 ml/min • Operating Pressures up to 1450 PSIA • High accuracy and repeatability • Storage of max. 8 calibration curves • User configurable control characteristics • Flow Parameter Adjust functionality up to 150 PSIA • Effective Rangeability <180:1 • Analog or digital: RS232, DeviceNet™, ProfibusDP®, Modbus-RTU ENGINEERING YOUR SUCCESS.

AT = k.Cp.0m AT = T2-T1 in Kelvin = specific heat 0m = mass flow Thermal Mass Flow Measuring Principle The Mass Flow Sensing System consists of a stainless steel capillary tube with two precision heater and temperature sensing elements wound around the outside of the tube. As gas flows through the capilliary tube, heat is displaced to the downstream temperature sensor creating a differential between the two sensors. The difference is directly proportional to mass flow through the tube. In the main flow channel, a patented laminar flow element package creates a restriction that forces a...

Note: Pin 4 and Pin 8 should be seperatly and connected to power common at the power supply. Note: When using a unit configured for a fieldbus or RS232 I/O, it is not possible to operate the instrument using analog I/O without changing the “control mode” parameter. (See users manual) Note: For hookup details of modbus, Profibus or DeviceNet communications, see users manual.
