Compound water meter

Compound water meter is a kind of measuring instrument which is widely used at present, its measuring range is wide, which is the outstanding characteristic of this kind of water meter. What we call a child water meter should be called a compound water meter or a combined water meter. This is a new type of water meter which combines large caliber water meter and small caliber water meter. In fact, However, with the demands of water departments for the recovery or sale of water charges, all domestic water meter manufacturers have carried out new development and transformation of this type of water meter. the multi jet water meters and woltman water meter are combined into one water meter, which is mainly composed of a flow control valve installed on the back of a horizontal woltman type large diameter water meter and by-pass connecting a small diameter rotary vane wheel meter or called multi jet water meter.

Compound Water Meter

Compound Water Meter Description

Induction register for better performance and safety
High rotation ratio with long life
Very accurate mass flow measurement for applications with large fluctuations
Designed to maximize revenue collection
Both the integrated design and the separate construction are an option for easy installation


The hybrid (combined) WPC meter uses a turbine meter on the main line and a proportional meter on the low flow line. The valve change controls the flow of water through a suitable measuring device. All water passes through the low flow meter before opening the valve. As the pressure increases, the valve opens, allowing water to flow through two meters. The movement of the measuring element is transferred to the driving magnet, which transfers the movement to the drive magnet in the sealed register. The magnet is connected to the gear system and converts the rotation into the volume manifold which is shown on the registration surface.


The WPC (combination) meters consist of a main housing, a turbine measuring element, a switching valve housing, a main box cover, a multi-jet counter and magnetic recording units.
WPC Compound (Combination) Multimeters with magnetic register, dry register type for commercial and industrial applications, have dimensions from Dn50 to Dn200 (only Dn80 and Dn100) designed to meet the international standard ISO 4064 Standard.


All materials in contact with water, consciously selected by known corrosion resistance;
Iron body with internal and external epoxy coating protecting against corrosion;
Register of the OBOTU indicator of the main counter for the most comfortable reading position;
Copper can register a super dry main meter with IP68 protection;
The removable and removable measuring mechanism of the main meter can be easily removed from the body for inspection, maintenance and replacement, there is no need to dismantle the body of the tube;
Lower Pressure loss;
No effected by external magnetic fields;
