Structure and Working Theory
Â
      Inside the counter of water meter (mechanical part), there is one magnet embedded under the wheel pointer for 0.01 m3 of water and two reed switches beside each side of the wheel. Each time the pointer goes a circle, one group of two pulses is generated to represent 0.01 m3 of water being calculated. The pulses are converted to digital signals and recorded as metering data based on pre-set program. Then the metering data can be transmitted to a concentrator or hand-held unit.

Plate And Shell Heat Exchanger
The plate and shell heat exchanger range of heat exchangers are new generation heat exchangers, combining the best properties of the Plate & Frame and Shell & Tube heat exchangers. The plate and shell heat exchanger provides high heat transfer rates with a high pressure and temperature operating range. They have no gaskets, are compact, low fouling and can operate at close approach temperatures.The application is Hydrocarbon condensers and evaporators;Heat-recovery exchangers like feed/effluent exchangers;Overhead condensers and gas liquefiers.
At the heart of the plate and shell heat exchanger is a fully welded pack of circular plates without gaskets. This plate pack is housed within a tubular shell to provide a strong compact construction. The plate and shell heat exchanger series have a very wide operating range with capacities of up to 100 MW / units, and can operate at pressures up to 100 bar and temperatures up to 400°C. They have a low maintenance design that provides flexibility to select different material and nozzle combinations.
