OVERVIEW: (per manufacturer) The Kurz Instruments 454FT series of insertion mass flow transmitters are point velocity sensing devices. This bivariable transmitter also measures the process temperature. The flow element is a constant temperature thermal anemometer which intrinsically measures the process fluid Reynold’s number. The net meter response is mass rate per unit area. The engineering output may be scaled to represent standard velocity, standard volumetric flow or mass rate. Density changes are automatically accounted for negating the need for pressure and temperature compensation. A complete description of how and what the thermal anemometer measures can be found in Appendix A. The units must be calibrated in the gas type to be measured or may be correlated from Air calibrations if available. The process temperature measured with this series will read accurately (within a few degrees C) above 100 SFPM (0.5 SMPS). The unit has an optional LCD/keypad local interface which can be used for complete setup, control and monitoring. The 454FT is a 3, 4 or 5-wire device whose 4- 20 mA output current is directly proportional to the flow rate. A second 4-20 mA output can be used for temperature or a different flow scale. The unit is available as 24 VDC, 115 VAC @ 50 to 60 Hz, or 230 VAC @ 50 to 60 Hz powered. The 4-20 mA output can be nonisolated self-powered or isolated loop-powered. The typical configuration has all the electronics in one enclosure, known as the TA configuration, or with just the sensor and a terminal wiring board in a separate enclosure from the electronics in the TS configuration. Both cases are shown in the field wiring diagrams. The TS configuration is used where the sensor enclosure ambient temperature is expected to exceed 65 °C, allowing the electronics to be mounted separately in a cooler place.
