Measurement of Discharge from Triangular and Rectangular Weirs and Other Open Channels

Weir-type flow volume calculation using the M series Free Programmable MXS (or VJXS) Computing Units

  • Support for a variety of weir calculations is achieved by adding the discharge calculations of weir-type flowmeters to the M series' basic expressions.
  • Because the water head and flow volume obtained in the calculation process are stored in the buffer registers, they can be confirmed using JHT200 handy terminal or VJ77 parameter setting tool.

  • These operations must be programmed by the user when using the free programmable model.
  • The MXS and VJXS do not include a power supply for transmitters. If you need to use a power supply for transmitters, please use a distributor.
