KOCF3000A Ultrasonic Open Channel Flow Meter – Integrated type
Instruction
The KOCF3000A ultrasonic open channel flow meter, together with measuring weir flume, is used to measure water flow in open channel. It is mainly used to measure the flow of sewage plant, sewage discharge outlet of enterprises and public institutions, urban sewers, as well as the channels for irrigation and water conservancy.
Feature
As for the meters produced by KACISE, the non-contact method is used for measurement by letting ultrasonic wave passing through air. Therefore, they are more reliable and durable in dirty and corrosive solutions compared with the contact-type meters.

| Probe selection | It is recommended to use a 100KHz M48×2 probe for No. 1-5 Parshall trough, with a measuring range of 2 meters (the length of the sensor line is less than 12 meters). The probe is not easy to hit the wall or corner of the Parshall trough to form false signals. The blind area of the M48×2 probe is small, only 13-15 cm, and the mounting bracket can be made even lower. It is recommended to use a 64Khz M48×2 probe for No. 6-25 Parshall trough, with a measuring range of 3 meters and a blind area of 30-40 cm. |
| Probe material | Standard made by ABS, and anticorrosive material shall be used for ones for the corrosive environment |
| Power dissipation of split type | 24V split type, the power is as follows: Only with mA output is 1.5W (standard configuration); Only with 485 output is 0.9W (optional); Simultaneously with 485 and mA output is 1.6W (optional); Adding two relays increases the power consumption by 0.8W on the original basis; 220VAC split type power is 5W. |
| Power dissipation of integrated type | 24V integrated four-wire model, the power is as follows: Only with mA output is 1W (standard configuration); Only with 485 output is 0.6W (optional); Simultaneously with 485 and mA output is 1.05W (optional); Add two relays, the power consumption is increased by 1W on the original basis; The 220VAC integrated four-wire model has a power of 5W. |
