Water meters' main function is to make the users more aware of the co nsumption of water. Choosing the appropriate meter is key to high quality water treatment.

AiMei takes a number of factors into consideration in determining the most suitable water meter type,

1. including water meter size 2. water meter class 3. water meter model 4. water meter type.

Water Meter Size
Water meter size depends on both pipe diameter and nominal flow rate (Qn). Nominal flow rate is normally half of maximum flow rate (Q max). For example, if the maximum flow rate is 5 cubic meters per hour (5,000 litres/hr), the nominal flow rate will be 2.5 cubic meters pe r hour. Thus 20mm (3/4") water meter will be suitable to this water system.

Water Meter Class


Water Meter has four classes, from Class A (lowest level) to Class D (highest level). Generally, the higher Class water meters can accura tely measure the water consumption at a wider range of flow rate than lower Class ones. For instance, 15mm Class C water meters start to measure the water consumption accurately at flow rate of 15 litres per hour, while 15mm Class A water meters do that since flow rate of 60 litres per hour only.

Water Meter Model


Water meter has different models, including Multi jet, single jet and rotary piston type. The selection of right model depends on the Class of water meter and target prices. Rotary piston type is mostly designed for Class C & D water meter. In contrast, Single jet and Multi jet water meters are normally Class A & B. The other factor is the price. In most cases, Rotary piston type water meter is the most expensiv e one, and Multi jet is the second, while Single jet is the cheapest.

Water Meter Type
Wet dial, liquid-sealed dial and dry dial type are three main types of water meters. All these three types of water meters are widely used worldwide. The selection may highly depend on historical use of water meter types in the area. One local water meter sample may be used for identification. If there is no water inside the water meter dial (face), it should be dry dial. However, if there is some water inside the water meter register, not the whole dial, it is liquid-sealed dial. Finally, if the water goes throu gh the whole dial, it will be wet dial. It is highly appreciated to send a photo of required water meter (old or installed water meter) with the inquiry. AiMei will check the photo and recommend the right water meter to you.

Plastic water meters are newly designed as an alternative option of brass water meter, mainly due to prevent water meter from stolen.

Plastic water meters are in small sizes and used in 1/2" (15mm) to 2" (50mm) sizes for residential and smaller commercial uses, which are increasingly used worldwide.
Plastic water meter body is made by thermoplastics via plastic injection, which is anti-corrosion.

Plastic water meters are clean and friendly to the environment.

Water meter reading

Different size meters indicate different resolutions of the reading. One rotation of the sweep hand may be equivalent to 10
gallons or to 1,000 gallons (1 to 100 ft.3, 0.1 to 10 m3). If one rotation of the hand represents 10 gallons, the meter has a 10 gallon sweep. Sometimes the last number(s) of the wheel display are non-rotating or printed on the dial face. The fixed zero number(s) are represented by the position of the rotating sweep hand. For example, if one rotation of the hand is 10 gallons, the sweep hand is on 7, and the wheel display shows 123456 plus a fixed zero, the actual total usage would be 1,234,567 gallons.

In the United States most utilities bill only to the nearest 100 or 1,000 gallons (10 to 100 ft.3, 1 to 10 m3), and often only read the leftmost 4 or 5 numbers on the display wheels. Using the above example, they would read and bill 1,234, rounding to 1,234,000 gallons based on a 1,000 gallon billing resolution. The most common rounding for a particular size meter is often indicated by differently coloured number wheels, the ones ignored being black, and the ones used for billing being white.

Registers

There are several types of registers on water meters. A standard register normally has a dial similar to a clock, with gradations around the perimeter to indicate the measuring unit and the amount of water used, if less than the lowest digit in a display similar to the odometer wheels in a car, their sum being the total volume used. Modern registers are normally driven by a magnetic coupling between a magnet in the measuring chamber attached to the measuring element and another attached to the bottom of the register. Gears in the register convert the motion of the measuring element to the proper usage increment for display on the sweep hand and the odometer-style wheels. Many registers also have a leak detector. This is a small visible disk or hand that is geared closer to the rotation speed of the drive magnet, so that very small flows that would be visually undetectable on the regular sweep hand can be seen.

With Automatic Meter Reading, manufacturers have developed pulse or encoder registers to produce electronic output for radio transmitters, reading storage devices, and data logging devices. Pulse meters send a digital or analog electronic pulse to a recording device. Encoder registers have an electronic means permitting an external device to interrogate the register to obtain either the position of the wheels or a stored electronic reading. Frequent transmissions of consumption data can be used to give smart meter functionality.

There are also some specialized types of registers such as meters with an LCD display instead of mechanical wheels, and registers to output data or pulses to a variety of recording and controller devices. For industrial applications, output is often 4-20 mA analog for recording or controlling different flow rates in addition to totalization.

Prepaid water meters

Meters can be prepaid or postpaid, depending on the payment method. Most mechanical type water meters are of the postpaid type, as are electromagnetic and ultrasonic meters. With prepaid water meters the user purchases and prepays for a given amount of water from a vending station. The amount of water credited is entered on media such as an IC or RF type card. The main difference is whether the card needs a contact with the processing part of the prepaid water meter. In some areas a prepaid water meter uses a keypad as the interface for inputting the water credit.
