KOCF3000B Ultrasonic Open Channel Flow Meter – Split type
Instruction
The KOCF3000B 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.
Dimension
| Functions | Integrated type |
|---|---|
| Process temperature | -20～+80℃ |
| Relay output | (Optional) 2 AC 250V/(NO:10A, NC:6A) or DC 24V/10A, state programmable |
| Power supply | (Optional) 12VDC, supplied by battery or solar energy |
| Working temperature | ≤90%RH, non-condensed |
| Measurement range | 0.1L/s~99999.99m3/h, according to flume |
| Accuracy of water level | 0.5% |
| Flow measurement accuracy | 1~5% for standard Parshall flume and triangular weir 10% for standard rectangular weir 10~50% for non-standard weir and flume |
| Max. scale value of water level | 1m, 2m, 5m, 10m. customizable |
| Resolution ratio | 3mm or 0.1% |
| Analog output | 4-wire, load of 4~20mA/510Ω |
| 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. |
| 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. |
| Working temperature | display instrument -20~+60°C, probe -20~+80°C |
| 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. |
