INTRODUCTION:
◆Model LXH-15、20 is the world’s favourite domestic water meter, with over 50 million already in service in over 100 countries, and offers accuracy, long life, low maintenance and tamperproof operation. Available in sizes 15mm and 20mm, it offer unrivaled performance to ISO4064 Class C or D.
◆Unrivaled accuracy in any position, for any flow
Due to the volumetric rotary piston measurement principle, its range can achieve the highest levels of reading accuracy even at the lowest flow rate. The meter can be installed in any position: horizontally, vertically or inclined pipelines, maintaining optimum performance with no loss of accuracy.
◆Robust, leak-proof construction
1. The use of advanced engineering plastics for the meter’s measuring chamber significantly reduces wear and helps maintain reliable, accurate measurement over all operating conditions. Solid particles are gathered by a large surface area strainer, Further preventing damage, and its advanced design ensures that partial obstruction of the strainer will have no ill effect on the accuracy of the meter’s registration.
2. A body ‘O’ ring seal between the measuring chamber and meter body ensures that internal leaks which could by-pass the measuring chamber are eliminated.
◆Easy to read
The counter is fully sealed, liquid filled using a vacuum and offers simple, straight-reading presentation. The number rollers are completely immersed in a lubricating non-toxic liquid, and a sac attached to the counter casing. Acts as a balancing membrane, ensuring the pressure of the liquid in the counter equals that of the external water. The counter window is inside the meter body in the direction of flow for simplified reading.
◆Tamperproof operation
1.The model LXH-15,20 offers unrivaled resistance to illegal tampering: its unique conical body-half design eliminates the risk of disassembly whilst in service and the mechanically driven cyclometer-type counter is resistant to magnetic interference.
◆Revolutionary grooved piston
Meter stoppages are substantially reduced, durability enhanced and performance improved as a result of a uniquely-designed grooved piston within the meter measuring chamber, increasing applications flexibility (available in 15mm and 20mm sizes).
◆Relative motion of the grooved piston.
Its action, with the stationary chamber wall, creates small flow eddies which hold solids in suspension until flushed out, reducing meter stoppages.
