REMOVABLE WOLTMAN WATER METER (MODEL D-SERIES DN50~DN200)
▪ The body is made from Ductile Iron with internal and external epoxy coating.
▪ The water meter have a wider flow range especially with lower minimum flow rate.
▪ Capable of having exchangeable measuring rang 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 a lower flow rate.
• 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 hydro static depends in 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 om shaft and indicating device, the rotation is impeller is transfer to indicating device to donate the total volume of water passing through the water meter.
