Horizontal Stainless Steel Water Meter

 

Product Introduction

Mechanical water meter is widely used in daily drinking water, a spiral type rotor and two main types,

detachable horizontal Woltman water meter for measuring instrument measuring total volume of water

flowing through the tap water pipe, hot water, sewage, and can not measure the corrosive liquid.

The rotary wing type wet water meter is a measuring instrument for measuring the volume of water

flowing through the water pipe, and is suitable for small industrial water and domestic water use.

The product is novel in design, reasonable in structure, precise in assembly and high in sensitivity.

The product is reliable in quality and convenient in maintenance. It is a common water meter for tap

water measurement.

Characteristics

The water meter is a dry water meter wheel, the display, the magnetic transmission between the

counting mechanism and the measuring mechanism, with advanced structure, easy reading,

small pressure loss, easy maintenance, the series of water meters can be attached to remote

transmitting device (double reed switch signal, pulse equivalent: 100 liters / 1000 liters / pulse, pulse......)

Technical parameters

Maximum permissible error: including minimum flow rate (Q1) and does not include the critical

flow (Q2) low area: + 5%; including the critical flow (Q2) to include the high overload

flow (Q4): + 2% (water + 3%)
Pressure loss: under overload flow, the pressure loss of water meter shall not exceed 0.063Mpa;
Water temperature: cold water table 0.1-30 DEG C, hot water meter 30-90 DEG c;
Working pressure: 1.0Mpa
Conditions of use: pressure loss grade: the P25 flow sensitive level: U10 D5

Implementation standards

CJ/T133-2012 "IC card cold water meter"; JJG162-2009 "cold water meter verification regulation";
GB/T778.1-2001/ISO4046-1:2005; GB/T778.3-2007/ISO4046-3:2005.

Application
--Measuring the volume of cold (hot) water passing through the pipeline.

Feature
--Removable element structure, easy installation and maintenance;
--Dry-dial, Magnetic drive;
--Large flow capacity, small pressure loss;
--Resist water hummer and pollution;
--Vacuum sealed register ensures the dial keep free from condensation and keep the reading clear in a long term service;

--Technical data conform to international standard ISO 4064.Class B

The meters can be equipped with a kind of remote transmission device, the pulse generating volume could be 100,1000 or 10000 L/pulse.

Working condition

Water temperature: 0.1℃~50℃ (0.1℃~90℃ for hot water meter)

Water pressure: ≤1.0Mpa (1.6MPa on request)

Maximum permissible errors

in the lower zone from qmin inclusive up to but excluding qt is ±5%

in the upper zone from qt inclusive up to and including qs is ±2% (±3% for hot water meter)
