| Product Information |
| Application,Features: |
Measuring the volume of cold potable water passing throught the pipeline.
This type water meter consists of basic water meter and aggregate pipe,and it connects with the pipeline by aggregate pipe.When taking a periodic inspect on the water meter online,it¡¯sno need of dismanting whole water meter down the pipeline,but replacing with the qualified basic water meter.The basic water meter is of of volumetric type on principle of piston rotation,it¡¯sof magnetic drive,long term clear reading,high accuracy,fitted with antimagnetic shield.

Installation and Application:
1¡¢The kind of water meter is not suitable for the uses in hot water;
2¡¢The location of installation shall be protected from exposure to sunshine,frost,pollution and submergence in water,in order to dismantle and write down the reading of the meter;.
3¡¢The kind of water meter can be installed in any directions (it will be better if the counter windows up to the sky);
4¡¢The kind of water meter has a high requirement on the water quality,it's unallowed if any granule and fibre sundries in the water.
5¡¢The newly-installed pipe shall be flushed so as to maintain neither sand,nor sediment in it before installation of water meter;
6¡¢When this kind of meter is installed,the arrow direction on the meter casing must coincide with the direction of the water flow;
7¡¢The meter should not be directly connected with pipe,but with coupling,gasket and nut.When dismantle meters,don't force to twist them for fear of damaging the body. |
