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.

1. Mineral Wool: Mineral wool is a popular choice for insulation due to its excellent thermal properties and fire resistance. It is available in various forms, such as blankets or boards, and can be easily cut and shaped to fit the heat exchanger.
2. Foam Insulation: Foam insulation, such as polyurethane or polystyrene, is lightweight and offers good thermal insulation. It is often used in applications where space is limited or weight reduction is desired.
3. Fiberglass: Fiberglass insulation is widely used in industrial applications due to its low cost and good thermal insulation properties. It is available in various forms, such as batts or loose fill, and can be easily installed around the heat exchanger.
4. Ceramic Fiber: Ceramic fiber insulation is known for its high-temperature resistance and low thermal conductivity. It is commonly used in applications where the heat exchanger operates at high temperatures.
When selecting insulation for a brazed plate heat exchanger, it is important to consider factors such as the operating temperature, space limitations, and fire safety requirements. Additionally, proper installation and sealing of the insulation are crucial to ensure maximum effectiveness.
