Precision Brass Class C Pulse-Ready Domestic Water Meters

Not every water project needs a fully smart meter from day one. Many homes, small businesses and sub-metering installations need a robust mechanical water meter that can be read locally today and integrated into pulse logging later. The Precision brass Class C pulse-ready domestic water meter fits that role well, especially where a traditional brass-bodied meter is preferred for durability and service familiarity.

Core specifications

The catalog describes this as a DZR brass-bodied semi-positive rotary piston water meter available in 15mm, 20mm and 25mm sizes. Length options include 114mm, 165mm and 198mm, depending on the selected size. The meter includes an internal strainer, non-return valve and sealed straight-reading wet dial counter registering in m3. It is pulse-ready at 1 pulse per half litre and is approved to Class C by the N.R.C.S. in accordance with SANS 1529-1: 2019 and section 22 of the Legal Metrology Act 2014.

Those details make it suitable for domestic and light commercial billing environments where a compliant, readable and serviceable meter is required. The pulse-ready capability is especially useful because it lets a site start with manual reading and later connect to a logger or monitoring system without replacing the core meter.

Use cases and benefits

Typical applications include residential sub-metering, small office units, staff accommodation, garden cottages and small business premises. The straight-reading counter keeps manual reads simple, while the internal strainer and non-return valve support more reliable operation when the meter is installed correctly with suitable upstream protection.

The brass body is often chosen where installers want a sturdy meter for exposed or higher-traffic service areas. The Class C approval is important for customers who need confidence that the meter is fit for formal consumption measurement rather than rough indication.
