Ultrasonic Flow Meter

An Ultrasonic Flow Meter (Gas Flow Meter) is an advanced, non-intrusive device designed to measure gas flow accurately using ultrasonic transit-time technology. It calculates flow rate by sending ultrasonic signals between sensors and measuring the difference in travel time caused by gas movement. Ideal for smart factory solutions, it ensures precise monitoring, zero pressure loss, and reliable performance.

OVERVIEW

The Ultrasonic Gas Flow Meter provides high-accuracy measurement with no moving parts, resulting in low maintenance and long service life. It supports real-time monitoring and seamless integration with industrial automation and IoT systems. Its non-contact measurement principle ensures minimal wear and high reliability. It is widely used for energy management, leak detection, and process optimization.

Working Principle

The Ultrasonic Flow Meter operates on the transit-time method. It sends ultrasonic pulses both upstream and downstream through the flowing gas. The difference in travel time between the two signals is directly proportional to the gas velocity. The internal processor calculates the gas flow rate based on this time difference without any moving parts or pressure drop.

Product Overview

Portable Ultrasonic Flow Meter

The Portable Ultrasonic Flow Meter is designed to measure liquid flow without direct contact with the fluid. By attaching the sensors to the outside surface of the pipe, it accurately detects flow without interrupting operations. Its compact design makes it easy to carry and use in various field conditions. This portable device is ideal for production monitoring, flow validation, and on-site inspection, making it an essential solution for real-time flow analysis. It is widely applied across industries such as municipal water supply, heating systems, water management, metallurgy, chemical processing, and energy sectors.

Wall-Mounted Ultrasonic Flow Meter

The wall-mounted ultrasonic flow meter is developed to measure the velocity of liquids flowing inside closed pipelines. It operates using clamp-on transducers that are installed externally on the pipe, eliminating the need to cut or modify the line. Because the sensors do not come into direct contact with the fluid, the system ensures clean, maintenance-free operation while offering quick and convenient installation.

Energy Meter

Ultrasonic Open Chanel Flow Meter

An open channel flow meter primarily measures the liquid level to determine flow rate. A measuring weir is installed within the open channel to facilitate accurate flow measurement. This weir converts the flow passing through the channel into a corresponding liquid level height. The device then monitors the water level in the channel or tank and calculates the instantaneous flow rate based on the established relationship between liquid level and flow characteristics of the specific weir or channel design.
