MJK Flow Converter 713

Product Features


  • MJK Flow Converter 713 for measuring and recording water flow in open ducts and channels.
  • A complete instrument for the measuring of instantaneous flow and recording of accumulated water flow.
  • Can be adapted to any type of weir or flume.
  • The sensor provides a signal proportional to the level.
  • The amplifier linearizes the signal from the sensor so it is proportional with the flow rate.
  • Calculate flow on the basis of one of the three principles: preprogrammed formulas for different dimensions of the most common flumes and weirs such as Parshall, Venturi and Palmer Bouwlus flumes and retangular or V-notch weirs based on ISO 1438; when using non-standard flumes or weirs the existing calculation formula can be programmed; for flumes where no calculation formula exists, a number of known Level-flow values can be entered, on the basis of these a point-linearization is made.
  • 5 output relays which can be configured for PLC and SCADA Interface.
  • The relay function can be set to external totalizers counter,control of samplerhigh flow ratelow flow ratemax. flow / hourmin. flow / hourmax flow /daymin flow / day andsensor error.

RBC Flumes
Eijkelkamp 13.17 RBC Flumes

Product Features
  • Eijkelkamp 13.17 RBC Flumes used to measure the quantity of water that, for instance, flows through an irrigation channel.
  • By comparison to known flumes, such as the WSC- and the Parshall flume, the RBC flume is the most accurate.
  • Designed for use in smaller water ways or earthen channels (irrigation channels, in- outlets, furrow, ditches, etc.).
  • A simple and reliable instrument for the measurement of the quantity of irrigation water that flows towards a field.
  • The standard program contains flumes with various measuring ranges,  varying from 0.1-8.7 l/sec to 2.0-145 l/sec.
  • 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 the 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 it is possible to install a pressure transducer connected to a datalogger.

V-NOTCH and Flow Meters
Sisgeo V-NOTCH and Flow Meters

Product Features
  • Sisgeo V-NOTCH and Flow Meters for water flow monitoring in open channels is widely employed in environmental and geotechnical field.
  • Leakage measurement is one of the most important indicator of the overall performance of earth/rock-fill and concrete dam.
  • The leakage rate is a function of the water level in the reservoir and depends either of the construction and of the behaviour of the dam.
  • Consequently, leakage monitoring provides data for the evaluation of the long term stability of the dam constructions.
  • Leakage water is usually impounded downstream of the dam and diverted to a basin in a weir-station.

Streamflo Velocity Meter
Nixon Streamflo Velocity Meter

Product Features
  • The Streamflo series of instruments are used to measure, indicate and record very low velocities of water and other conductive fluids.
  • Designed primarily for laboratory and specialised industrial use, the miniature head of the flow sensing probe can be inserted into small ducts and channels where it has the ability to measure velocities as low as 5.0 cm/sec.
  • It is thus suitable for measuring accurately the velocities in hydraulic models of river estuaries, dams, harbours, etc., in addition to field measurements of clean water flows.
