Description
The domestic plastic water meter – pulse ready – 20mm is a durable and accurate water meter designed for measuring cold potable water consumption in domestic properties and small business applications.
This 20 mm polymer-bodied semi-positive rotary piston water meter is approved to SANS 1529-1:2019 Class C specifications and is designed to provide reliable water consumption measurement in residential and small commercial applications.
The meter features a clear liquid-filled 8-digit counter for easy reading, pulse-ready functionality, an internal strainer and a spring-loaded non-return valve. The meter body is manufactured from specially blended, glass-reinforced UV-stabilised polymer, providing a durable and lightweight alternative to conventional metal water meters.
The 20 mm model also features a bowed strainer with increased mesh area to help improve debris filtration within the meter. With a working pressure of up to 1600 kPa, this meter is suitable for a wide range of domestic and small business cold-water applications.
