weir flow meter introductory

Kingmach’s introductory weir flow meters stick to the essentials. They use thin-plate weir structures built to common notch profiles—rectangular, V-notch, or trapezoidal—based on widely published discharge equations. This means you can install one and start getting flow readings without elaborate on-site calibration. Our standard packages include a well-crafted weir plate, a bracket system for easy mounting in concrete or earthen channels, and a float-type or submersible level sensor matched to the expected head range. Output options are usually 4-20mA or Modbus, feeding straight into your existing PLC or logger. Accuracy in the field typically sits within a few percent, which is enough for process control or billing applications where a ±2—5% error band is acceptable. Where things get a bit more tailored: plate thickness can be adjusted for debris-heavy flows, the stilling well size can be modified for turbulent inlets, and we can coat plates with epoxy or other finishes for corrosive waters. Because we manufacture a wide range of monitoring instruments, you get a supplier who understands the broader measurement chain, not just the weir. We also keep common spare parts in stock, so you aren’t stuck waiting. Whether it’s a small V-notch for a spring measurement or a wide rectangular weir for a canal, we work with you to match the hydraulics to your actual flow range. Support is available from our technical team at any stage, from initial sizing to field wiring. It’s not the most advanced flow meter out there, but if you need something that works and keeps working, it’s worth a look.
