Product Introduction

The valve-controlled integrated flow meter is a high-end integrated flow instrument that integrates flow measurement, valve control, and signal transmission. It deeply integrates high-precision flow measurement technology with mature valve structures to achieve "metering plus control" integration. It is widely used in municipal water supply, heating, chemical engineering, metallurgy, environmental protection, water conservancy, and other fields, making it an ideal solution for intelligent and streamlined operation and maintenance of modern fluid pipeline networks.

Working principle

Valve-regulated ultrasonic flowmeter

Using the ultrasonic time difference measurement principle, the flow rate and flow rate are accurately calculated by measuring the time difference between the propagation time of ultrasonic signals in the fluid with and against the current. Measurement pipe sections, sensors, transmission units, and control valves are highly integrated, enabling on-site installation in one step, significantly shortening construction cycles and reducing system complexity.

Valve-regulated electromagnetic flowmeter

Based on Faraday's law of electromagnetic induction, when a conductive liquid flows through the measuring tube, it induces a voltage signal proportional to the flow rate, which is converted into a flow value by a high-precision processing unit. Highly integrated sensors, transmitters, control valves, and display units reduce pipeline joints and lower leakage risks.

Introduction to functional technology

Core advantages

High-precision measurement: measurement accuracy ±0.5~±1.0%, repeatability better than ±0.2%

No pressure loss, low energy consumption: No internal moving parts, no interference with flow field, no pressure loss

Integrated control: local/remote switching, regulation, and shut-off—one valve serves multiple purposes

High protection and long service life: valve body materials available in carbon steel/304/316, protection rating IP68

The valve core ball material can be selected as high-strength nylon, 304, or 316

Display and communication

Equipped with a 2.8-inch high-definition LCD display, it shows real-time parameters such as instantaneous flow, cumulative flow, flow rate, temperature, pressure, current, voltage, electricity consumption, and amount. Supports communication methods such as 4-20mA, RS485 (Modbus-RTU), pulse output, HART, and more, seamlessly connecting to DCS, PLC, and smart water platforms.

Power supply and battery life

Powered by a built-in high-performance battery, specially designed for well-electric dual control, remote machine wells without electricity, and farmland irrigation scenarios. Intelligent low-power hibernation operation, with sleep power consumption reduced to the μA level, and typical scenario battery life can reach 2-3 years. Supports offline data caching and uploading, ensuring data loss and full traceability.

Remote monitoring platform

Supports remote real-time monitoring via mobile phone, remote control, intelligent alarms, and dual-control closed-loop management of well and electricity. Real-time viewing of equipment status, water and electricity data, supports mobile phone timing, quantitative control, automatic over-limit locking, abnormal automatic reminders, or valve closure.
