WI Series DN40-300 Agricultural Irrigation Sewage Water Meter

 Product features/advantages

• Small transmission resistance, large flow capacity, anti block and strong anti-pollution ability;

Engineered for minimal head loss, delivering exceptional flow capacity. Built with robust anti-clogging and anti-pollution performance to handle the harsh, sediment-laden water common in irrigation systems.

 

. Vacuum sealed register ensures the dial keep free from condensation and keep the reading clear in a long term service;

The hermetically sealed register is completely protected against condensation, fogging, and moisture ingress, ensuring accurate and easy-to-read measurements for years, even in high-humidity environments.

 

• Dry-dial,Magneticdrive;

The magnetic drive mechanism eliminates direct contact between the wetted parts and the register, preventing corrosion and wear, while the dry dial ensures clear visibility at all times.

 

• Removable measuring unit and strong universality, easy installation and maintenance;

The cartridge-style measuring unit can be easily removed for inspection, cleaning, or replacement without removing the entire meter from the line. This reduces downtime and maintenance costs significantly.

 

• Remote transmission device can be added upon request, such as Reed Switch or Hall, Pulse Output:

The meter can be customized with remote communication devices upon request, including Reed Switch or Hall Effect sensors for pulse output, making it easy to integrate into automated irrigation and monitoring systems.

 

• Photoelectric direct reading register output interface; RS485 or M-bus, NB register: Magnetic, Non-magnetic.

Equipped with a photoelectric direct reading register, and available with RS485, M-Bus, or NB-IoT communication modules. Both magnetic and non-magnetic register versions are available to suit any Automatic Meter Reading (AMR) system.

 

• Technical data conform to ISO 4064 standard.

All technical specifications are rigorously tested and conform to the ISO 4064 international standard, ensuring proven accuracy and reliability
