Product Introduction

I. Overview

The MGG/KL-DPL Doppler Flowmeter adopts a proprietary sensor excitation system and high-performance signal processing system, equipped with a 32-bit embedded ultra-low-power processor and full digital signal processing technology. The device features stable operation, high measurement accuracy, and strong anti-interference capability. It supports automatic bidirectional flow measurement, on-site multi-parameter display, and self-diagnostic fault alarm functions, with optional digital interfaces and storage modules. All operations are performed via the touch screen interface.

The MGG/KL-DPL series is our company’s portable Doppler velocity and flowmeter product line, which includes three models:
Type I: Features basic velocity and flow measurement functions.
Type II: Integrates advanced mathematical models to calculate average velocity, and simultaneously measures instantaneous flow rate and accumulated flow during operation.
Type III: High-performance measurement system equipped with an integrated water depth sensor, enabling comprehensive collection of water depth, velocity, and flow data.

II. Functional Features
(Note: "Class II" refers to Class II/III flow; the device supports both velocity and flow measurement)

Stability & Reliability: The velocity sensor has no moving parts, completely eliminating the risk of debris entanglement and ensuring long-term continuous and reliable operation with full functionality.
Low Power Consumption & Long Battery Life: With low-power design, the device can operate continuously for more than 50 hours on a single battery replacement, facilitating long-term on-site measurement (flowmeter is Type II; water depth sensor is optional).
High-Definition Touch Display: Equipped with a high-definition backlit touchscreen and full Chinese menu, it offers simple operation and clear visibility both day and night.
Full-Parameter Display: The interface simultaneously displays flow rate, accumulated flow, water level, flow direction, power consumption, alarm information, operating time, and working status.
Multiple Measurement Modes: Supports pole-mounted measurement, rope-suspended measurement, and mobile measurement to adapt to different on-site working conditions.
Energy Saving & Environmental Protection: Features an automatic screen-off function (customizable settings available) to further reduce power consumption.
