Types of Bulk Water Meter
The bulk water meters produced by our company mainly include the following types

Irrigation Water Meter
An irrigation water meter is a separate water meter used specifically to measure water consumed for outdoor purposes like lawn watering, pool filling, or irrigation, and it helps reduce sewer charges. Unlike the main water meter that measures water used inside the home (which is typically billed for sewer usage), an irrigation meter measures water that doesn't enter the sewer system.

Compound Water Meter
A compound water meter is a type of meter designed for applications where both high and low water flows need to be accurately measured. It combines two metering technologies – a positive displacement meter for low flows and a turbine meter for high flows – along with a valve system to switch between them based on the flow rate. This ensures accurate measurement across a wide range of water consumption.

Batch Control Water Meter
A batch control water meter is a system that accurately measures and controls the amount of water dispensed in a specific, preset volume, often for batch processes like mixing concrete or chemicals. It typically consists of a flow meter, a controller, and an actuator (like a valve or pump). The controller is programmed with the desired batch size, and the system automatically opens the valve/pump, measures the water flow, and then shuts off the flow once the target volume is reached.
Features of Bulk Water Meters
Wide Range of Flow Capacities
Available in sizes from 40mm to 600mm, these meters support flow capacities from 20 m³/h up to 5000 m³/h, catering to various large-scale needs.
Built-in Pulse Output
Integrated pulse output enables easy connection to remote monitoring systems, offering greater flexibility for water management
Direct Reading Register
The meters feature a direct reading register across all sizes, simplifying manual reading processes.
Class B Accuracy with Low Pressure Loss
The helical vane design substantially exceeds Class B requirements for accuracy, ensuring precise water measurement even at high flow rates.
Robust Construction
The cast iron body is epoxy-coated for enhanced durability and protection from corrosion.
Hermetically Sealed Register
The register is hermetically sealed to IP68 standards, ensuring reliable performance in tough environments.

Bulk Water Meter Installation Steps
Check the site: First, look where you want to install the meter. Decide on the size of the meter to be used and where it will be. Make sure that the surroundings around the pipes are prepared for installation.
Prepare for installation: Shut off the main water supply to prevent leaks. Cut the pipe where the meter will be placed. Clean the ends of the pipe so they’re suitable for the fittings.
Install the meter: Attach the meter to the pipe, ensuring the meter’s parameters are aligned with the water flow. After that, secure the meter to the pipe and tighten everything so it doesn’t hurt the meter.
Test the meter: Slowly turn on the water supply; check for any leaks around the meter. Run some water through the meter and test if the reading is proper. If necessary, adjust the meter to make sure it’s accurate. Meter cover: If your meter is located outside, back the cover or lid to protect it from weather elements.
Regular maintenance: After installation, the meter should be frequently checked to ensure the meter is working continuously and has exact readings.
