Multi-jet type water meter with liquid filled register
An inferential, multi-jet, water meter for cold water. The meter has a straight reading register which is located in a liquid filled counter.
The impeller rotates in a measuring chamber (distributor) with a double raw of tangential holes.
The chamber is made of self cleaning synthetic resin.
The Beta-Mj-Lfc water meter offers the following advantages:
- The straight reading register is contained in a liquid filled sealed housing which is not subject to discolouration by scale, dirt or any deposit. A special device prevents air bubbles distorting the reading over the counter numerals. Easy reading in any working conditions is ensured.
- The meter is suitable for operation in hard water and under conditions where deposits may occur.
- A long operating life thanks to the robust construction, which provides maximum protection, to a very low number of impeller revolutions per cubic metre of water flow and to the selection of high quality materials.
- Mechanical transmission movement assures absolute reliability.
- Excellent hydraulic performance, EEC approval 75/33 (Class B and C).
- The meter can be installed on horizontal, vertical and inclined pipes.
