DOL 90 Water Meter

The DOL 90 Water Meter is designed for precise monitoring of water consumption, making it easier to detect leaks, abnormal usage, or excessive animal water intake. It integrates seamlessly into any cold‑water system and provides both mechanical and electronic measurement options.

Key Features
  • Accurate Pulse‑Based Measurement
    • Factory‑calibrated to generate one pulse per liter

    • Supports accumulated and delta pulse counting

    • Ideal for logging, automation systems, and remote monitoring

  • Durable Construction
    • Built with a robust composite polymer housing

    • Includes an integrated inlet filter to protect internal components

    • Designed for long‑term reliability in agricultural and industrial environments

  • Dual Reading Options
    • Mechanical counter on the device for direct visual reading

    • Electronic pulse output via an integrated switch for external counters, PLCs, or data loggers

How It Works

Inside the DOL 90, a small impeller rotates as water flows through the pipe.
    • The rotation speed is proportional to water volume over time

    • A gear system transfers this motion to the mechanical counter

    • A magnet on the gear activates an electrical switch, generating pulses for digital monitoring

This combination provides both real‑time mechanical indication and precise electronic measurement.
LoRa Version Available
The DOL 90 is also offered in a LoRa-enabled version, allowing long‑range wireless transmission of water‑usage data. This is especially useful for:
  • Remote barns or pastures

  • Large livestock operations

  • Facilities where wired connections are impractical
