Tongtuo presents the LXLC series Mechanical Irrigation Water Meter, specifically engineered for large-scale agricultural water management. This robust Irrigation Water Meter combines Woltman turbine technology with heavy-duty construction, delivering reliable performance for irrigation districts, agricultural cooperatives, and large farm water allocation systems.
Key Features
High-Capacity Water Measurement
Designed for large-volume irrigation applications with flow rates from 5-3000m³/h, ensuring accurate measurement for agricultural water billing
Mechanical Irrigation Water Meter Reliability
Pure mechanical drive system requires no external power, ideal for remote agricultural settings with limited infrastructure
Removable Cartridge Design
Patented removable element allows maintenance and calibration without pipeline disruption, reducing downtime during irrigation seasons
Pulse Output Options
Configurable pulse functionality: non-pulse, active pulse output (1000L/pulse), or pre-equipped for future automation upgrades
Vacuum-Sealed Register Protection
Dry dial with magnetic drive maintains reading clarity in humid irrigation environments, preventing fogging and moisture damage
Agricultural-Grade Construction
Heavy-duty cast iron body with epoxy coating withstands agricultural water conditions and outdoor installation
