Brass Kent type Water Meters – PISTON (Rotary/Volumetric – e.g., Kent types)
Overview
The Domestic Brass Piston Meter comes in 15mm, 20mm or 25mm. It is 114mm, 165mm or 198mm long and is fitted with an internal strainer and a non-return valve. The sealed wet dial counter registers in m³. The meter is pulse-ready (1 pulse per half litre). Approved to Class C by the N.R.C.S. in accordance with the requirements of SANS 1529-1: 2019 and section 22 of the Legal Metrology Act 2014 (Act 9 of 2014).
Key Features
- Robust DZR brass body, tamper-resistant with glass viewing window
- Rotary piston mechanism—accurate over wide flow range; Class C or D per ISO 4064/SANS 1529
- Available in sizes DN15–DN40; flow rates from ~6 L/h up to ~20 m³/h
- Optional pulse output (AMR/IoT) for remote monitoring 15mm,20mm or 25mm
- Internal strainer
- Non-return valve
- Sealed wet-dial counter
Technical Specifications
- Pressure rating up to 16 bar
- Operating temp up to 50 °C
- Accuracy in any orientation, thanks to grooved piston design
Applications
- Domestic water supply in homes and small buildings
- Coastal or chemically aggressive environments where metal corrosion is a concern
- Prepaid water metering and AMR installations
- Cost-effective metering in new housing developments
Plastic Kent type water meter Overview – V-RANGE
Overview
The Plastic Kent Water Meter is a compact, lightweight, and corrosion-resistant solution ideal for residential and light commercial metering. Designed with the same precision engineering as the brass Kent V-series, this meter uses a volumetric rotary piston mechanism housed in a high-grade polymer composite body, making it especially suitable for coastal, humid, or chemically aggressive environments.
Key Features
- Volumetric piston design for high accuracy, even at low flow rates
- UV-resistant engineering plastic body – durable and non-corrosive
- Compatible with pulse output modules for AMR/remote monitoring
- Dry dial with clear display and tamper-proof sealing
- Conforms to ISO 4064 / SANS 1529 standards (Class C or D)
Technical Specifications
- Size Range: DN15 to DN25
- Flow Range: 5.7 L/h to 5 m³/h
- Pressure Rating: Up to 16 bar
- Operating Temperature: Up to 50 °C
- Connection Type: BSP threaded (typically supplied with couplings)
- Mounting: Horizontal or vertical
Applications
- Residential metering → taps, toilets, boilers
- Light commercial/plumbing systems
- Network monitoring with AMR capability
BRASS Helix TYPE / Woltmann Meters (Bulk Industrial Brass)
Overview
The Helix-Type Water Meter, also referred to as a Woltmann meter, is built for high-volume water measurement with excellent durability, low head loss, and accurate performance. It uses a horizontal rotor (helical turbine) that spins proportionally to the flow rate, making it ideal for bulk water supply systems, irrigation schemes, and municipal distribution networks.
Key Features
- High-capacity Woltmann turbine mechanism
- Dry dial display with vacuum-sealed counter to prevent condensation
- Low-pressure loss with stable accuracy over a wide flow range
- Pulse output available for remote monitoring (AMR/BMS/SCADA integration)
- Reversible flow – accurate measurement in both directions (optional)
- Long service life with minimal maintenance requirements
- Complies with ISO 4064 / SANS 1529 standards
Technical Specifications
- Size Range: DN50 to DN300
- Flow Range: 0.35 m³/h up to 2,000 m³/h (varies by size)
- Pressure Rating: Up to 16 bar
- Operating Temperature: Typically up to 50 °C (cold water)
- Body Material: Epoxy-coated cast iron or ductile iron
- Rotor Material: Stainless steel or high-performance polymer
- Connections: Flanged PN10 or PN16
- Installation: Horizontal (standard) or vertical (with accuracy trade-off)
Applications
- Municipal bulk metering
- Industrial water supply and cooling systems
- Agricultural and irrigation schemes
- Pump stations and storage tank inlet/outlet metering
- Utility network monitoring with remote data capture
