2 Design Hydrodynamic Mechanism Independent The operation of the Hydrotangential meter is based on a turbine at the top of the meter, which allows the solid particles go through without obstructing the meter. There are no obstacles in the measuring tube, therefore pressure loss are very low. With a completely independent mechanism and protected against magnetic ﬁelds, the Hydrotangential counter allows a simpler repair, without having to extract water meter from the installation, greater durability and security against fraud.

Water Engineering Its operation is based on a turbine or propeller located at the top of the measuring tube.

3 High ﬂow rate The system on which the Hidrotangencial counter is based is designed to provide a high ﬂow rate with the minimum pressure loss. Water Engineering Its operation is based on a turbine or propeller located at the top of the measuring tube. The rotation of the propeller is transmitted by magnetic transmission through a shaft and gear to a head that accumulates in its totalizer the volume of water circulated through the water meter.

9 Diagrams for installing Water disrupting elements upstream from the meter. DN= Ø water meter. Required length upstream from the meter = L With flow-correcting cartridge Without flow-correcting cartridge L=5DN L=5DN Centrifuge pump 3DN L=0DN Sluice valve fully open Sluice valve being adjusted L=0DN L=3DN L=5DN L=3DN L=0DN L=3DN L=5DN L=3DN L=0DN L=3DN Screen ﬁlter Elbows T-joint The precision of a Hidrotangencial can be aected by turbulence due to such elements as elbows, regulator valves, T-joints, etc.; consequently, in these cases a straight section is required before the meter. However, this straight section can be reduced or replaced by a ﬂow-stabilising cartridge upstream from the meter and connected to it. Reduction cones Expansion cones Installation instructions - It is recommended to place the watermeter at a low point in the installation - Place the meter so that the arrow matches the direction of the water ﬂow. - Do not force the meter during assembly; avoid tension or torsional stress, especially to the threaded connections. - The meters must always be full of water when operating and installed below the slope of the rest of the pipeline. This stops air pockets from forming inside. - 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. A new pipeline should be drained before ﬁtting a meter to eliminate particles. - The meter connection can be instaled on horizontal, oblique or vertical pipe. - The inside diameter of the pipe must be equal to the nominal diameter of the watermeter. - If there is air in the pipeline, suckers must be ﬁtted to avoid incorrect readings.

11 FAQ - Has the turbine broken? The rupture of the turbine may be caused by the presence of solid particles of considerable size, for example, blocks and stones which may be suspended in the water. In this case you must replace the counter mechanism and place a ﬁlter before the counter so it does not happen again. 2- The water meter does not add up? It is likely that it is stuck, has some internal part damaged or has suﬀered wear and tear due to aging. When an aging wear occurs, the meter may add up to m3, but not the actual ones. In this case, the damaged element must be replaced. Our counters thanks to its hydrodynamic design with independent mechanism makes this type of repairs very simple. Tip: have complete mechanisms to replace the faulty meter while it is being repaired Al rights reserved. Copyright. 206 HIDROCONTA. S.A.
