IFLO Irrigation Water Meter
Description
Valvelink, your trusted partner for all process control needs, is proud to introduce the IFLO Irrigation Water Meter, Model LXXG-50-600. This robust instrument is expertly designed for the critical task of measuring the total volume of water flowing through your irrigation pipelines, ensuring accuracy and reliability in water management.
The IFLO Irrigation water meter is engineered to perform under demanding conditions, making it an ideal solution for agricultural and large-scale landscape applications.
Key Features and Advanced Characteristics
The IFLO Irrigation water meter is built with features that guarantee longevity, accuracy, and ease of use:
- High Flow Capacity and Durability: The meter is designed with small transmission resistance, allowing for a large flow capacity. Its strong anti-blocking and anti-pollution capabilities ensure consistent performance even in challenging water conditions.
- Reliable Drive Mechanism: It utilizes a horizontal rotor with a dry, magnetic coupling drive, providing dependable operation.
- Clear and Consistent Readings: The counter is vacuum-sealed to prevent condensation and atomization, ensuring the reading remains clear over a long period.
- Simplified Maintenance: A removable structure allows for straightforward installation and maintenance, minimizing downtime. The measuring mechanism also features strong universality.
- Remote Monitoring Capabilities: For modern data management, the meter can be equipped with a remote transmission device (double reed / hall transmission) to meet specific customer requirements.
Installation and Operating Conditions
To ensure optimal performance and accuracy, the IFLO Irrigation water meter has specific installation and operational guidelines:
- Installation: The meter must be installed horizontally. It requires an additional water filter to protect the mechanism. A straight pipe section of at least 10 times the diameter upstream (U10) and 5 times the diameter downstream (D5) is necessary for accurate flow measurement.
- Operating Conditions: The meter is available in sizes from DN50 to DN600 and is housed in a durable cast iron shell. It accommodates various operational demands with temperature grades of T30, T50, and T90, and pressure classes of MAP16 and MAP10.
