Sanchuan’s Bulk Water meter (DN40–DN300) delivers wide-range R200–R630 accuracy, low pressure loss, IP68 durability, NB-IoT/pulse/RS485-ready for remote integration—ideal for industrial and municipal bulk water metering.
Woltman meters utilize a rotary helical impeller that spins with flow. Movement is magnetically coupled to a sealed dry register or pulse transmitter, offering robust, wear-free measurement in large-diameter pipes.
Model: HP5D (DN40–DN300)
Flow Range: R200, covering 0.315 – 2000 m³/h
Accuracy: ISO 4064 Class B
Construction: Epoxy-coated body, IP-rated, robust for harsh environments
Variants: Horizontal/vertical installations, pulse or inductive outputs, remote communication
Install inline strainer upstream to protect the impeller
Mount the meter horizontally or vertically, ensuring upward flow if not horizontal
Ensure adequate straight pipe runs and secure flanges per specifications
Connect pulse or communication modules (e.g., NB-IoT, M-Bus, RS485) for remote reading
Select appropriate DN size based on required flow rates and range (e.g., DN40+ for 63–2000 m³/h).
Ensure accuracy class meets ISO 4064 Class B standards.
Decide on output functionality: choose pulse, inductive, or communication module depending on AMR/SCADA needs.
Confirm installation orientation (horizontal vs vertical) and environmental resilience (IP rating).
Verify accessory compatibility, such as inline strainers and remote modules, for scalable deployments.
Bulk flow meters are used to accurately measure large water volumes—such as for hydrant fill-ups, irrigation districts, or industrial feed lines. They ensure correct billing, monitor water transfer, and support non-revenue water reduction through precise flow tracking.
A bulk water meter measures large-volume water flow in distribution systems—often DN50 to DN300 using Woltman or ultrasonic technology. It’s designed for high flow rates, minimal pressure loss, and durable operation in industrial or municipal settings.
A bulk water system refers to high-capacity water supply setups, such as hydrant fill stations or main pipelines feeding multiple buildings or resale networks. It often includes infrastructure like tanker access, permitting, and large meters to manage wholesale water delivery.
