Ultrasonic flowmeters are known for their high accuracy, reliability, and suitability for various industrial environments. They offer a non-invasive method of measuring fluid flow, making them ideal for applications where minimal disruption is required. One of the key advantages of ultrasonic flowmeters is their ease of installation compared to other types of flowmeters. The process typically involves selecting an appropriate measurement point, entering the pipe parameters into the device, and securing the sensors onto the pipe surface.
To ensure accurate and stable measurements, the sensor installation should be placed on a straight section of the pipe where the fluid flows uniformly. The pipe must be fully filled with liquid during installation. It's important to choose a location where the fluid is homogeneous and easily transmits ultrasonic waves. Ideal locations include vertical sections (with upward flow) or horizontal sections. The installation site should be at least 10 diameters upstream and 5 diameters downstream from any valves, elbows, or reducers. Avoid areas near pumps, valves, or electrical equipment that may cause interference.
Additionally, it’s crucial to avoid installing the flowmeter at the highest point of the system or in vertical pipes with free outlets, as this can lead to air bubbles or improper flow. For open or partially full pipes, the flowmeter should be installed in a U-shaped section to maintain proper contact with the fluid. The temperature and pressure at the installation point should remain within the operational range of the sensor. Also, consider potential fouling of the pipe walls—try to install the meter in a clean area. If scaling is unavoidable, consider using a lining to improve measurement accuracy.
The two sensors must be installed horizontally along the pipe axis, within ±45° of the horizontal position. This helps prevent issues such as air bubbles or sediment accumulation, which could affect measurement performance. If horizontal installation isn't possible due to space constraints, the sensors can be mounted vertically or at an angle, as long as no air bubbles are present in the upper part of the pipe.

Piston Seals
Piston seal is a kind of seal used to seal between piston and cylinder, usually used in hydraulic system and Pressure system. The piston seal can prevent liquid and gas leakage, and also prevent external impurities from entering the system, thus maintaining the normal operation of the system.
Piston seals can be classified based on their structure and material. According to different structures, piston seals can be divided into unidirectional seals and bidirectional seals. A unidirectional seal can only prevent the leakage of liquid or gas from one direction, while a bidirectional seal can prevent the leakage of liquid or gas from both directions. According to different materials, piston seals can be divided into rubber seals, polyurethane seals, polytetrafluoroethylene seals, etc.
In hydraulic systems, piston seals are typically used to seal hydraulic cylinders and pumps. The piston seals in hydraulic systems need to have characteristics such as high temperature resistance, corrosion resistance, and wear resistance to ensure long-term stable operation of the system. In Pressure system, piston seals are usually used to seal cylinders and pumps. The piston seals in the Pressure system need to be resistant to high pressure, low temperature, wear and other characteristics to ensure the normal operation of the system.
In addition to hydraulic system and Pressure system, piston seals can also be used in other industrial fields, such as automobile, aviation, machinery, etc. In the automotive industry, piston seals are commonly used in engines to ensure normal engine operation. In the aviation industry, piston seals are commonly used in the hydraulic system of aircraft to ensure normal takeoff, landing, and flight. In the field of machinery, piston seals are commonly used in hydraulic and press machines to ensure the normal operation of the machine.
In short, piston seals are a very important type of seal that is widely used in various industrial fields. With the continuous development of industrial technology, the materials, structure, and performance of piston seals are also constantly improving and upgrading to meet the needs of different fields.
