Model TVP-15E~20E water meter for Cold water

Is designed by Timely Co.engineer seasoned in water meter and manufactured by using advanced technology,in which, the register device is combinated pointers and rolling counters which is convenient, clear and correct for reading as well as nice appearance.

The register system is designed by means oflow speed magnetic-drive avoiding magnetic coupling slip in high flow rate however remainig high sensitivity in low flow rate, hermetically sealed invaccum condition, completely separated with pipeline water.

The T type water meters are high accuracy of measurement, steady error curve of whole range flow rate, the performance is more advanced than existing traditonal design water meter.

APPLICATION:

Measuring the volume of cold potable water passing through the pipeline.

 FEATURES:

External adjusting, DryDial, None foggy register, AntiMagnetic and AntiSlip, Low speed magnetic drive,pointer-roller indicator, easy and long term clear reading, long work life etc.Inlet strainer and Outlet non return valve, Available with remote output bypulse on request. Preparation for pulse 1litres/pulse.

 WORKING CONDITION:

Water temperature: ≤50℃ for cold water meter

Waterpressure: ≤1.6Mpa

MAXIMUM PERMISSIBLE ERROR:

Inthe lower zone from Qmin/Q1 inclusive up to but excluding Qt /Q2 is ±5%

Inthe upper zone from Qt /Q2 inclusive up to and including Qmax /Q4 is cold water meter ±2%.

NOTE:Technical data conform to International Standard ISO4064.

INSTALLING AND USING:

When using it, if there are impurities (cotton fibre, scraps of paper, silt, etc.)in the pipe, which make the inlet strainer easily stopped up. And if you findthe water meter goes fast or slow, even stops, you should go to the Water authorities to have it overhauled regularly in one or two years.

1. Thoroughly flush theservice line upstream of the meter to remove dirt and debris.

2. Remove meter spud threadprotectors.

NOTE: To protect the meterspud threads, store the meter with thread protectors in place.

3. Set the meter in theline. Install the meter in a horizontal plane, with the register upright, in alocation accessible for reading, service and inspection. Arrows on the side ofthe meter and above the outlet spud indicate the direction of flow.

4. Do not overtightenconnections; tighten only as required to seal. Do not use pipe sealant orTeflon tape on meter threads.

5. If meter is equipped with an electrical contacting head register, line up molded tabs on inside ofreed switch with corresponding indentions of receptacle on face of meter.Insert reed switch and turn 1/4 turn to lock in place.

6. Tie black and red wireson opposite end of reed switch to corresponding black and red water meter wireson controller. Insulate connection with water-proof wrapping.

7. With upstream shutoffvalve only:

Open shutoff valve slowly,to remove air from the meter and service line. Open a faucet slowly to allow entrapped air to escape. Close the faucet.


With both upstream and downstream shutoff valves installed:

To test the installationfor leaks: Close the outlet (downstream) shutoff valve. Open the inlet(upstream) shutoff slowly until meter is full of water.

Open the outlet(downstream) valve slowly until air is out of meter and service line. Open afaucet slowly to allow entrapped air to escape. Close the faucet.
