Water Meters & Strainers

Water meters are used to measure quantitative flow of water. We have in ready stock capstan water meters of all sizes, both for Domestic use and Bulk type. These meters are designed for durability, Accuracy of registering continuous flow and long life. Their quality policy backed by QC engineers ensures that quality control at all stages of manufacturing enables only the top class products to enter the market. All capstan meters confirm to IS 2373. We can supply capstan meter at very competitive rates.

Types of meter available with us :

  • Capstan Domestic meters
  • Capstan Woltman meters
  • Capstan Spiral meters

 

Domestic water meters: Multi jet , Dry dial , class ‘B’

Water Meters & Strainers

Features :

  • Capstan water meter has robust design, All meters are precise and highly durable
  • High quality corrosion resistant materials are used. Special importance in manufacruting all movable parts.
  • Magnetic Coupling drives the roller counter which is completely separated from water and always remains clean and easily readable even under adverse conditions.
  • The rotor is the only part which moves in water. It has a defined two point bearing and runs on sapphire jewel bearing.
  • Equally spaced tangential holes in the measuring chamber through which the water flows and impinges on the impeller equally on all sides. There being no side thrust the bearing wear is reduced to its minimum.
  • Suitable for water temperature upto 45’C
  • Capstan meter offers high measurement sensitivity and accuracy.
  • Conforms to class “B” of ISO : 4064/1 and IS : 779 1994 and are ISI marked.

Capstan Spiral Water meter

Water Meters & Strainers

Features :

  • Meters upto 100mm have ISI mark
  • Designed to meet demand of reliable meters, capable of measuring large quantities of water , where little loss of water head is allowed .
  • Meter casing is of graded cast iron and houses press fitted non removable liner made of brass .
  • Spiral meters are tested to withstand a maximum hydrostatic pressure of 16 kg/cm2 .
  • Suitable for maximum temperature of 45’C
  • High Overload capacity .
  • All meters are designed to measure water even when pipe is full.

Installation :
In Horizontal & Oblique .

Requirements before installation :
Unrestricted straight pipe before the meter 10 X DIA . No abrupt restriction immediately behind meter thus for long durability Installation of strainer before the meter is recommended. Performance Table as per ISO 4064/1 of 1993 Class B

Precautions :
1) Please note meter should not be buried underground if they are buried please make sufficient cabinet for periodic reading and its safety .
2) Non-Return (Check) Valve on outlet side of the watermeter is preferable .
3)Take due care while meter mounting and unpacking as all meter have movable parts inside and can get damaged due to jerks or fall causing deviations in readings for which we are not responsible .
4) External strainer must be installed on inlet side of the water meter to avoid any particulate going it to the meter and choking and effecting efficiency of reading .

Calibration :
We can supply all capstan meter with test certificate for its accuracy and rage ability i.e Meter to be Tested at Meter Testing Department of B.M.C at extra cost only Time required 2 weeks.

Water Meters & Strainers
Water Meters & Strainers

 

We at ambuja tube fitting recommend for domestic or industrial water meters to be installed with strainers before water meter mounting place as it removes soild flowing wastes in liquid mechincally in its wire mesh therby safeguarding instruments , pumps , valves , water meters etc Strainers are like dirt boxes which collects dirt particulate waste moving in liquids or gas . Strainers are available in Sizes ranging from 50mm to 600mm can be quoted on request .
