LXLY Woltmann Cold Water Meter
General introduction:
Our LXLY woltmann cold water meter is a horizontal woltmann-type meter designed for measuring bulk flows of cold potable water for revenue billing in commercial or industrial applications and district metered area (DMA) management, leakage monitoring, and consumption analysis of distribution monitoring system.
The electronic register and mechanic base are designed within one integral structure which is more reliable and easier for installation. The electronic register is self-powered by its own internal battery. This LXLY woltmann cold water meter is manufactured according to the ISO 4064:2005 and BS 5728 standards.

Robust Construction
The LXLY woltmann cold water meter is manufactured from the highest quality materials for maximum resistance to wear and corrosion. Meter body and cover are coated with epoxy powder for protection in all environments. Thrust pads and stub spindles are manufactured in tungsten carbide for maximum wear life. All wetted materials do no harm to human health.
Intelligent Meter Reading
Fully compatible with Wasion’s data collection device of intelligent meter reading systems, LXLY electronic bulk woltmann cold water meter can provide even more vital management information to assist with effective distribution management, reduce water losses from leakage and improve customer service.
In-line Strainer
The use of an in-line strainer is recommended to protect the rotor and help reduce the effect of turbulence.
