The Chemitec 4204/P is an ultrasonic flow meter designed for open channel measurement using flumes or weirs (such as rectangular, Cipolletti, Thompson, Venturi, Parshall, and Leopold Lagco), with options for free exponential calculation or a user-set multipoint table. It measures flow from 0 to 9999 mc/h, level from 0.30 to 5.00 meters, and temperature from -25 to +75.0 °C. Housed in an IP 65 ABS container measuring 144x144x122.5 mm for wall assembly, the unit features a backlit LCD STN 128x64 graphic display, a 6-key programming keyboard, a 4 Mbit flash data logger, and non-volatile Flash ROM storage. It includes two 0/4-20mA analogue outputs, five independent digital set point relay outputs, one cumulative alarm relay output, and an RS485 serial output with native MODBUS RTU protocol. Power supply is 90-260Vac 50-60Hz with optional 24Vac/dc.
