Stainless steel RBC flume, with stilling well for manual measurements or installation of a pressure sensor. The RBC flume is a reliable instrument for the measurement of the quantity of irrigation water that flows towards a field. Four sizes with various measuring ranges are available, varying from 0.1-8.7 l/sec to 2.0-145 l/sec. On special order larger measuring ranges are possible as well.
RBC flumes are used to measure the quantity of water that flows through a certain place, such as an irrigation channel. The RBC flume has been specially designed for use in smaller water ways or earthen channels (irrigation channels, in- outlets, furrow, ditches, etc.). Royal Eijkelkamp offers a trapezium shaped RBC flume for four flow rate ranges. Compared to other well-known flumes, such as the WSC and the Parshall flume, the RBC flume is the most accurate.
Trapezium shaped flumes have two important advantages:
Thanks to its small weight and dimensions, the flumes can be easily used and transported. This is particularly advantageous in the event of multiple temporary measurements.
The following variations and measuring are available. Larger ranges can be made to order.
In order to obtain correct measurements it is essential that the flume is placed in such a way that the water can flow from the flume without obstruction. After the flume has been placed in a horizontal position, measuring can begin by reading the measure of water surge near the threshold. The measure of water surge can be read in the stilling well at the end of the flume.
Using standard formulas the flow through quantity (the discharge) is calculated.
Instead of reading the stilling well manually, it is also possible to install a pressure transducer connected to a datalogger. This allows for automatic measuring (or activation), storage and reading. In case of an automated flume, the sill-referenced water level is recorded using a very accurate pressure sensor connected to a datalogger. Automatic registration instead of manual determination of the flow rate provides the following advantages:
The software enables you to configure and to read out the data directly. The data can be used in spread-sheet programs. The user-friendly PC-software has the following functions:
You can even connect the datalogger to a modem (such as the GDT-S Prime) in order to have the measured data transferred. Contact our sales team to find the most suitable logger and modem for your situation.
