Kurz - Model Series 155 -Mass Flow Computer/Transmitter

The various models operate one or more Kurz Mass Flow Elements including Series 452, 502, 522-UHP, K-BAR 16, K-BAR 24, K-BAR 2000, the Series IK-4200 Isokinetic Sampling Probes and the Series 730 Mass Flow Control Valves .

The Series 155 may also be used with the new MFT Series of Mass Flow Transmitters (454FT, 504FT, 534FT, K-BAR 2000) as a convenient power supply, display and Mass Flow Computer for remote sensor electronics applications.

The Series 155 integrates the functions of flow and temperature measurement, flow totalization, alarms, data acquisition, input/output calibration and closed loop flow control. Models are available to operate up to 22 separate two-wire, loop-powered Kurz mass flow or temperature elements. The smaller Model 155`s have two analog 4-20 mA outputs; the larger models support up to eight 4-20 mA outputs. All Models include a convenient 2 line, 16 character LCD display and 20 button keypad to display the measurements, input all calibration and set-up data, and perform input/output calibration of each input and each analog output.
