Product catalog summary
Introduction
The TW Series tangential water meters, produced by TECNIDRO in Italy, are designed for applications involving raw water, such as agricultural irrigation, gardening, and waste waters. These meters feature a tangential impeller, magnetic transmission, removable mechanism, adjustment device, pulse emitter, and instant flow visualization capabilities.

Specifications
The TW Series meters are available in different models:
  • TWP/TWM Series: Made from cast iron or ductile iron, these meters can withstand a maximum pressure of 16 bar (232 PSI). They are available with flanged or threaded connections and have either plastic or metallic covers.
  • TWN Series: Constructed from 30% fiberglass reinforced Nylon 66, these meters handle up to 10 bar (145 PSI) and are suitable for raw water and chemical mixtures. They are lightweight and easy to assemble.
The counting mechanisms and dials are interchangeable across different body materials.

Technical Data
The TW Series meters ensure precision measurement with an accuracy of ±5% for certain flow rates and ±2% for others. They are designed to meet ISO 16399 standards and are available in various sizes and weights, with specific flow rate recommendations.

Parts List
The meters consist of several components, including the cover, counter mechanism, baffle plate, magnetic torque, impeller, and body.

Instant Flow Rate Indicator
The IST indicator is an electronic device that measures instantaneous flow rates. It is powered by a replaceable lithium battery and can display flow in different units. The IST is available in two versions: compact (IST-C) and separated (IST-S), both designed for total immersion and compatible with TW Series meters.

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 the...

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).

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 added...
