Nitrogen Flow Controllers are devices specifically designed for measuring and controlling nitrogen flow. They not only measure the volumetric or mass flow rate of nitrogen, but crucially, they also control the flow rate. Generally, they are based on a nitrogen flow meter, with the addition of an automatic control valve and a closed-loop control system. … Read more
Measuring flow in large pipes with insertion type flow meters. If you need to measure the fluid flow of a larger pipe diameter, you are most likely to choose an insertion type flow meter. But what insertion type flow meter should you use? The market has insertion electromagnetic flowmeter, insertion vortex flowmeter, insertion ultrasonic flowmeter, … Read more

Portable density meters are used to measure the density or concentration of liquid media. Density or concentration measurement is an important process control in product manufacturing. Portable density meters can also be used as indicators for other quality control parameters such as solid content or concentration values. They can meet various measurement requirements of users … Read more
Ultrasonic gas flow meter is based on the transit-time measurement principle. It features built-in digital temperature and pressure transmitters, integrated wireless communication module, and combines flow measurement, volume correction, and remote data transmission in one velocity-type gas metering instrument. Key advantages include high measurement accuracy, excellent reliability, low pressure loss, and wide turndown ratio. It … Read more
Insertion turbine flow meters are devices that combine a sensor and a display instrument. They come in two structures: with and without a shut-off valve. They are widely used for measuring the flow rate and total volume of liquids such as raw water, circulating water, and purified water in large-diameter pipelines. Based on the sensor … Read more
The SI-3207 small turbine flow meter is specifically designed for measuring small-diameter pipes and low flow rates. It can be used to measure both instantaneous and total flow rates of liquids. Available in sizes from DN2 to DN10. Flow rates range from 30L/h to 160L/h. Customization options include a displayless design, a Hirschmann electrical interface, … Read more
The MXGF high-temperature gas flow meter is a flow meter specifically designed for measuring the flow rate of high-temperature gases. Its operating temperature ranges from -25°C to +800°C (1472 °F), and with special materials, it can reach 1500°C (2732 °F). Features Technical Parameters Performance Technical Specifications Structure Insertion Type Measurement Medium Suitable for various gases … Read more
By Li Rui, Senior Process Engineer at Sino-Inst | Published 2026-03-24. If you’ve ever had an ultrasonic level sensor fail prematurely, there’s a good chance the probe material was wrong for the job. I’ve seen this happen more times than I’d like to admit — a perfectly good sensor, installed in a sulfuric acid tank, … Read more
