METERDI offers a wide range of ultrasonic flow meters for industrial and commercial flow measurement applications. Designed for accuracy, portability, and ease of use, our flow meters provide non-invasive, maintenance-free solutions for measuring liquid flow in closed pipes.
A clamp-on ultrasonic flow meter measures fluid flow without cutting or drilling pipes. It uses sensors that attach externally to the pipe surface. These sensors send and receive ultrasonic signals to calculate the flow rate based on the time difference of the signals traveling upstream and downstream. This non-invasive design allows easy installation and maintenance without interrupting the flow.
The ultrasonic flow meter working principle is based on the measurement of the velocity of a fluid using ultrasonic sound waves. There are two main types of ultrasonic flow measurement technologies: transit-time and Doppler. The most widely used method in clean liquid applications is the transit-time principle. In this method, two ultrasonic transducers are placed on opposite sides of a pipe—one upstream and one downstream. These transducers function both as transmitters and receivers. When a signal is sent in the direction of the flow, it travels faster than the signal sent against the flow direction. The flow meter accurately measures the time it takes for the ultrasonic pulses to travel between the two sensors in both directions. The difference in transit time is directly proportional to the velocity of the fluid flowing inside the pipe. Since the internal diameter of the pipe is known, the meter uses this information to calculate the volumetric flow rate. The entire process is non-intrusive, meaning there is no contact with the fluid, no moving parts, and no pressure drop, making ultrasonic flow meters highly reliable, especially for applications involving clean water or chemical liquids. Some advanced models also offer ultrasonic flow meter working principle with diagram and real-time visualizations to enhance user understanding. This technology enables accurate, efficient, and maintenance-free flow measurement across various industries including water treatment, HVAC, oil and gas, and manufacturing.
Ultrasonic flow meters are widely used across various industries for accurate and reliable measurement of both liquid and gas flow. In water and wastewater management, they help monitor flow rates without interrupting operations. Oil and gas pipelines rely on them for safe, non-intrusive flow monitoring, even in high-pressure environments. In HVAC systems, these meters optimize energy use by measuring chilled or hot water flow. The chemical and pharmaceutical industries benefit from their ability to measure corrosive or high-purity fluids without contamination. Food and beverage processing plants use ultrasonic flow meters to maintain hygiene and process control. They are also essential in energy and utility monitoring, ensuring efficient resource distribution. Thanks to their clamp-on, non-invasive design, ultrasonic flow meters are ideal for retrofitting and measuring flow in existing pipelines without the need for cutting or system shutdowns.
Ultrasonic flow meters offer several key advantages that make them a preferred choice in many industries. Their non-intrusive measurement method eliminates the need for pipe cutting or process shutdown, making installation quick and cost-effective. With no moving parts, these meters require minimal maintenance and deliver long-term reliability. They provide high accuracy and repeatability, even under varying flow conditions. Ultrasonic flow meters are versatile and capable of measuring a wide range of fluids, including water, oil, chemicals, and other industrial liquids. Additionally, portable ultrasonic flow meters are available for temporary setups and field diagnostics, offering flexibility and convenience for on-site measurements.

When purchasing an ultrasonic flow meter, it’s important to consider your specific application needs, such as the type of liquid, pipe size, and installation environment. For clean fluids like water or chemicals, a transit-time ultrasonic flow meter is ideal, while Doppler models are better suited for liquids with suspended solids or air bubbles. Choose between a portable clamp-on model for temporary or mobile use, and a fixed inline or wall-mounted meter for continuous monitoring. Ensure the device supports your pipe material and diameter range, and look for features like high accuracy (±1% or better), data logging, battery operation, and easy calibration. Non-invasive models are preferred for their ease of installation and maintenance-free operation. Always buy from a reliable supplier like METERDI, which offers local support, free technical consultation, and fast delivery across India—making your purchase smooth, cost-effective, and future-ready.
