Domestic Water Meters

The Apollo DS Series water meters are designed to measure the volume flow of cold potable and service water.

Low cost
Long life bearings
Extended flow range
Simple calibration
Wet dial mechanical counterRN Turbine Flowmeter

 

Application
Water meters are installed by local water authorities to bill water usage. These DS series meters are suitable for fitting at domestic dwellings, agricultural and horticultural premises as well as industrial and commercial properties. They may be used for numerous applications where the accurate and economic measurement of cold water throughput is needed.

Totaliser
The direct reading counter is located within the pressure housing and is fitted with three dial counters which provide a resolution of 0.0005 m3 (i.e., 0.5 litre).
A five digit mechanical counter indicates the volume passed in cubic metres. The counter gears are located in a small chamber which protects the mechanism against any solids contained in the water.

Principle of Operation
The DS series is a mechanical inferential meter using the multi-jet principle. It is fitted with an integral direct reading wet dial counter to totalise the volume passed.

Construction
The water meter body and head are manufactured from brass. The main bearing, roller and pinion spindles are stainless steel. The remaining parts of the measuring element are high grade plastic. This sub-assembly including the multi-blade fan is supported on a sapphire bearing. All materials used within the water meter fully comply with strength and anticorrosion requirements to give complete resistance to chemically aggressive water supplies and continuous trouble free operation.

Calibration
All Apollo DS series water meters are individually check calibrated. They may be easily recalibrated by means of a by-pass screw which is accessible from outside of the meter. A security seal is fitted.

Installation
Apollo water meters are suitable for installation in horizontal pipelines and should be fitted such that the arrow marked on the body corresponds with the direction of water flow. The water meters should be easily accessible to enable a clear reading from the counter. The upstream pipework should be rising such that the outlet should always be higher than the meter inlet.

Options
There is a range of equipment for use with the S series flowmeters. These include air eliminators, check valves, filters and counters.
