Tangential Water Meter TECNIDRO® TW Series Tangential Water Meters TW Series

III The TW series water meters, manufactured in Italy by TECNIDRO, are specifically designed for all applications with raw water, in particular, agricultural irrigation, gardening and waste waters. The impeller measures the flow speed and its rotation is transmitted to a screen for the visualization of the total recorded volume. This class of measurers adopts an innovating technology that differs from the traditional equipment, characterizing itself by the following particularities: !Tangential Impeller: it is similar to a windmill immersed and placed in tangential position with respect to...

TANGENCIAL WATER METERS TW Series TWP/TWM Series The TWP/TWM Series tangential watermeters are manufactured in cast iron (EN-GJL 250) or in ductile iron (EN-GJS 500) in order to work to a maximum nominal pressure of 16 bar (232 PSI). The reinforced design and the materials grant a long life cycle and optimal performances. The new body design grants light and resistant meters. These watermeters can be manufactured with different connections, flanged or threaded, with different standards (EN/ASME/BS). The cover can be of plastic material (TWP) or metallic painted (TWM). TWN Series The TWN...

III TANGENTIAL WATER METERS TW Series Technical Data The water meters TW series assure a precision measurement of ± 5% for flow rates between [Q1] and [Q2] and a precision of ± 2% for flow rates between [Q2] and [Q4]. It is recommended to install water meters whose nominal flow rate [Q3] is in the same range of the pipe project flow rate.

III TANGENCIAL WATER METERS TW Series Instant Flow Rate Indicator The instant flow rate indicator IST manufactured by TECNIDRO® is an electronic device that measures the time that interruns between the pulses generated by an emitter type reed and it turns it into instantaneous volume. The equipment is powered by a replaceable long life lithium battery. When there is flow in the pipe, IST indicator activates and visualizes in a digital screen the instantaneous flow expressed in [l/s] or [m³/h] or [Gpm], accordingly to the configuration of firmware realized in factory. IST Indicator can be...
