Selecting water meters on sizes which normally fall into one of two groups.
Most familiar water meters are mechanical meters that use a rotor that will turn as the flow of water increases. These meters come in small and larger sizes and are a popular option for drinking water and other domestic or commercial uses – often seen in agriculture and irrigation.
How Water Meters Work?
Water meters are commonly used to provide a pulsed output once a certain volume has been measured. The pulse can be set to activate at the turning of the cycle or cycles of the rotor (sometimes called turbine) and this can be totalized on a counter to give the combined volume of water that has passed through the meter over a time period e.g. hours, days, weeks, months and years.
What are the types of water meter?
Most of the water meters available are of the mechanical type as described above.
Why cannot we use a water meter for everyday application?
The water meters cover a range of sizes but since they are mechanical, there is a limitation to the range of measurement normally with a maximum of 3-5 m/s depending on the manufacturer. All these meters (even from different manufacturers) are very simple to install and read, hence their popularity.
We will help our customers choose a water meter with a size that is suitable for the flow rate that they will be measuring.
It is important to check the flow velocity range of each meter if you intend to buy a water meter. In other words. We are making sure that the flow rate being measured does not exceed this. It might also be important to check the minimum readable flow velocity.
Residential water meters are a commonly bought product in the Philippines and the price list for the water meter will also depend on the quantity. For example, the price for a 2” water meter can vary considerably if a comparison is being done between purchasing only 1 water meter or 100,000 pieces.
If you would like for us to assist in the selection of a new water meter for an application that has had no previous meter installed, the following answers to these questions will be useful in speeding up an offer.
Questions such as:
- Minimum and Maximum Flow Velocities (or gallons per minute)
- Pipe Size and Material
- Temperature of the Water min/max
- Maximum Pressure Water Type e.g. Tap water, de-ionized water, demineralized water, distilled water, wastewater, sea water etc.
- Is the water relatively clear of particles?
