Compatible with JIS, capable of flow calculations for triangular weirs, rectangular weirs, broad-crested weirs, partial flumes, and other HQ rating tables.
The 『WW4486』 is a converter that calculates and outputs flow rate values based on water level. The types of weirs that can be calculated include triangular weirs, rectangular weirs, broad-crested weirs, and partial flumes. It is equipped with a function to absorb abnormal voltages, such as lightning, which can easily be induced in the connected cables, protecting the internal circuit and preventing feedback to the connected devices of the output signal. 【Features】 ■ Displays measurement values on the built-in LCD screen ■ Easy to change settings and perform maintenance on-site ■ Lightning protection: 10kV between input signal and case ■ Outputs flow rate values as a 4-20mA DC signal *For more details, please download the PDF or feel free to contact us.
