1 WTER METERS

2 Hydrodynamic design High protection Multi-jet technology ensures uniform distribution of load on the turbine located thanks to the water inlet diffuser. The movement activates the magnetic transmission that will give the final reading of the volume. Hidroconta Hydrojet watermeters are designed to avoid external manipulation by magnetic fields. They have a special shield that covers the dial and prevents any possible fraud.

3 Homologation for irrigation Thanks to the homologation acquired, the low maintenance needs and the reduced pressure losses this product is suitable for totalizing water for irrigation and hydraulic public domain. Pre-equiped The Hidrojet dial has a pre-installation that allows to place a pulse emitter, without having to stop the counter, this will give information of the reading.

4 Dial Metrological class: - in horizontal position. - upright. HIDROCONT m³ lining figures dial. pproval for use in irrigation water and hydraulic public domain. Qn.,m³/h -V -H E x, 6 4 x, 6 4 x 6, 6 4 x 4, Rotary starwheel for leak detection. Technical specifications - Metalic body epoxy coated. - Turbine and dial in thermoplastic material. - Vacuum dial to prevent condensation of water. - Magnetic transmission protected against external magnetic fields. - Pre-installation of pulser for remote reading. Quick connection without stopping or dismantling the meter. - High mechanical and wear resistance. - C.E.E. Class in horizontal and Class in vertical position. - Straight sections are not necessary at the Hidrojet input or output U-D.

9 Diagrams for installing U D Straight sections are not necessary at the Hidrojet input or output U-D. Installation instructions - Place the meter so that the arrow matches the direction of the water flow. - The meters must always be full of water when operating, minimum presure, bar, and installed below the slope of the rest of the pipeline. This stops air pockets from forming inside. - If there is air in the pipeline, suckers must be fitted to avoid incorrect readings. If the water in the pipeline contains large suspended particles, an initial screening filter should be installed. - Fit a valve upstream from the meter to facilitate maintenance or repair. - new pipeline should be drained before fitting a meter to eliminate particles. - Do not force the meter during assembly; avoid tension or torsional stress, especially to the threaded connections.. - The meter connection can be instaled on horizontal, oblique or vertical pipe.
