With AMR [AUTOMATIC METER READING]

 

 

Technical Specifications
 
Dimension and Accuracy Curve
 

This type of removable woltman water meter is specially manufactured with dynamically balance turbine to be sensitive for wider range of flow rates. This water meter can be equip with IP68 and install with an option for radio frequency type register.

 

APPLICATIONS
Accurate measurement of water volume passing through the pipeline.
Capable for inductive meter reading technology with robust wireless data transmission.
   
WORKING CONDITIONS
Water Temperature : 50°C up to 70°C
Water Pressure : 1.6 MPa
   
GENERAL DESCRIPTION OF PATTERN
The Removable Woltman Water Meter are meant for the metering of water and classified under accuracy Class 2.
The principle of this meter are operated based on the Flow Velocity of water detected by impeller which can laterally move along impeller’s axis in the flow direction.
The water meter consists of ductile iron body, exchangeable measuring units with impeller, and indicating device complete with gearing system.
This water meter are not design to measure reverse flow.
The water meter can be install and operate in arbitrary position.
   
   
FEATURES
The water meter can be install and operate in arbitrary position.
This water meter have a wider flow range especially with lower minimum flow rate.
Capable of having exchangeable measuring range i.e. R160 to R400
The register can be rotated in any position.
Inter-exchangeable parts.
The meter require 10 diameter and 5 diameter length for inlet and outlet respectively.
High sensitivity at lower flow rate.
   
MEASURING PRINCIPLE : FLOW VELOCITY USING IMPELLER
The working principle is based on impeller that rotates and moved laterally along the axis in the flow direction. The movement of this impeller along the axis is hydrostatic depends on the flow rate. The impeller will move forward along the axis in high flow rate but return back to original position under lower flow rate.
The rotation of the impeller is attached to a worm gear which is connected by shaft to indicating device. Using a permanent magnets on shaft and indicating device, the rotation of impeller is transfer to indicating device to denote the total volume of water passing through the water meter.
