handheld ultrasonic flow meter MT-F210UL

Description

1. Introduction to Handheld Ultrasonic Flow Meter MT-F210UL

The handheld ultrasonic flow meter MT-F210UL is a portable, highly accurate measuring device designed to provide flow measurement for a wide variety of pipeline systems. This device is based on the transit-time ultrasonic measurement principle, making it ideal for non-intrusive, clamp-on installation without the need to cut pipes or interrupt flow. With its wide measuring range and compatibility with different pipe materials, the MT-F210UL is a preferred choice in industries such as water supply, energy-saving projects, petrochemical plants, metallurgy, and heating systems.

Unlike mechanical flow meters, the handheld ultrasonic flow meter MT-F210UL has no moving components. This ensures low maintenance requirements, longer operational life, and stable measurement performance, even in demanding conditions. Its flexible transducer selection allows the device to adapt to pipe diameters from small to very large-scale distribution pipelines.

2. Working Principle

The MT-F210UL operates using the transit-time ultrasonic principle. This method measures the time difference between two ultrasonic signals that travel in opposite directions through the flowing medium. When liquid flows in a pipe, the signal moving with the flow travels faster than the signal moving against it. By calculating this time difference, the device determines the flow velocity. This measurement is then converted to volumetric flow rate.

This method is accurate and reliable because it does not depend on the fluid’s pressure, temperature, density, or viscosity. It also avoids issues like clogging or wear, which are common in mechanical sensors.
