Water meters are used to measure the volume of water used by residential and commercial building that are supplied with water by a public water supply system. Water meters can also be used at the water source, well, or throughout a water system to determine flow through a particular portion of the system. In most of the world water meters measure flow in cubic metres (m3)
There are several types of water meters in common use. The choice depends on the flow measurement method, the type of end user, the required flow rates, and accuracy requirements.
There are two common approaches to flow measurement, displacement and velocity, each making use of a variety of technologies. Common displacement designs include piston and disc meters. Velocity-based designs include single- and multi-jet meters and turbine meters.
There are also non-mechanical designs, for example electromagnetic and ultrasonic meters. Most meters in a typical water distribution system are designed to measure cold potable water only. Specialty hot water meters are designed with materials that can withstand higher temperatures. Meters for reclaimed water have special lavender register covers to signify that the water should not be used for drinking.
Additionally, there are electromechanical meters, and Energy Calculation Meters. Mechanical water meters normally use a reed switch, hall or photoelectric coding register as the signal output. After processing by the microcontroller unit (MCU) in the electronic module, the data are transmitted to the LCD or output to an information management system.
GRP panel tanks for water storage
Sheet Molding Compound (SMC) is a mixture of unsaturated polyester resin with impregnating augmentation material, filling material and glass fiber.
The SMC water tank body (floor, wall and ceiling) is made of bolting type square SMC panels, which are molded under high heat & pressure.
SMC water tanks guarantee sanitation, excellent durability, absolute water tightness, versatile capacity design and easy installation.
SMC water tanks meet the Food Sanitation Act. Bacteria or germ formation and growth are prevented by blocking sunlight transmission completely.
The internal tie-rods in stainless steel are coated with PE by heat-shrink tubing process, which provides stronger corrosion resistance. The external components are hot dip galvanized steel, which gives semi-permanent life.
*ABSOLUTE WATER TIGHTNESS
The foam type gasket with excellent elasticity and resilience assures perfect water tightness.
*VERSATILE CAPACITY DESIGN
Various panels make installation of tanks possible in any dimensions or capacities. (L-shape, U=shape, square-shape)
The installation of tank is very user-friendly even in the restricted area by using standardized bolting type panels.
*OUTSTANDING INSULATION PERFORMANCE
Pre-insulated panels are also available as an option. By using the PU foam insulated panels, the temperature change of the water in the tank can be minimized at high or low environmental temperature.
