1. Product introductionTDSP double-channel external clamp ultrasonic flowmeter is a double-channel ultrasonic flow measurement product adopting American technology. Each channel can achieve measurement accuracy. Double-channel redundancy greatly improves the accuracy and stability of the flowmeter, and overcomes the defect that mono-channel products are not suitable for flow field changes and have low accuracy and unstable flow. The measurement principle is still based on the time delay method. Due to the optimized design of two channels, the influence of turbulence randomness on measurement is overcome to a great extent, and the adaptability and measurement accuracy to different working conditions are greatly improved, making small flow measurement more guaranteed.In addition, the TDSP double-channel external clamp ultrasonic flowmeter uses advanced digital signal processing technology to make the dead angle of sensor design very small, and it is not easy to accumulate impurities such as rust and scale, thus solving the biggest hidden danger of interference of common ultrasonic flowmeter by impurities such as iron filings and welding slag, and being especially suitable for water quality with high impurity content.TDSP double-channel external clamp ultrasonic flowmeter uses a high-speed DSP processor to make the response speed of the measurement system less than 0.1 second, which is more than 10 times faster than the common flowmeter. It can be used as a quantitative control measurement standard, especially suitable for flow measurement of high viscosity oil, chemical products and ultra-pure water. It can also be connected with two temperature sensors as calorimeters. When more heat function is needed, GFM can also be used as the flow measurement part of calorimeter and connected to the calorimeter through 4-20mA as the flow measurement part.1.2 Product Features★ Flow measurement adopts double-channel ultrasonic technology to ensure measurement accuracy and stability;★ Adopt high-speed DSP processor, with response speed reaching 0.1 second;★ Advanced digital signal processing technology, the measurement is not interfered by iron filings, welding slag and other impurities;★ Different sensors can be connected to solve the problem of multi-bubble application on site1.3 Technical Indicators Technical indicatorsApplicationMeasurable liquidMost single-phase liquids.

Brief Introduction of Integrated Electromagnetic Flowmeter Products;Intelligent electromagnetic flowmeter is an electromagnetic induction type flow meter with nominal diameter ranging from 10 to 3000. It is a series of electromagnetic flowmeter products integrating intelligence, small size, light weight, multifunction, high precision and high reliability. It consists of sensor and intelligent converter.The intelligent electromagnetic flowmeter is suitable for measuring liquid-solid two-phase fluid containing solid particles or fibers due to its smooth straight pipe with a measurement channel that is an open flow detection piece and is not easy to block. At the same time, the electromagnetic flowmeter does not generate pressure loss caused by flow detection, and the resistance of the meter is only the resistance along the pipeline of the same length, so that the energy-saving effect is remarkable, and the electromagnetic flowmeter is most suitable for large-diameter water supply pipelines requiring low resistance loss; The volume flow measured by electromagnetic flowmeter is not affected obviously by the changes of fluid density, viscosity, temperature, pressure and conductivity (as long as it is above a certain threshold value).

1. Product introductionTDSP double-channel external clamp ultrasonic flowmeter is a double-channel ultrasonic flow measurement product adopting American technology. Each channel can achieve measurement accuracy. Double-channel redundancy greatly improves the accuracy and stability of the flowmeter, and overcomes the defect that mono-channel products are not suitable for flow field changes and have low accuracy and unstable flow. The measurement principle is still based on the time delay method. Due to the optimized design of two channels, the influence of turbulence randomness on measurement is overcome to a great extent, and the adaptability and measurement accuracy to different working conditions are greatly improved, making small flow measurement more guaranteed.In addition, the TDSP double-channel external clamp ultrasonic flowmeter uses advanced digital signal processing technology to make the dead angle of sensor design very small, and it is not easy to accumulate impurities such as rust and scale, thus solving the biggest hidden danger of interference of common ultrasonic flowmeter by impurities such as iron filings and welding slag, and being especially suitable for water quality with high impurity content.TDSP double-channel external clamp ultrasonic flowmeter uses a high-speed DSP processor to make the response speed of the measurement system less than 0.1 second, which is more than 10 times faster than the common flowmeter. It can be used as a quantitative control measurement standard, especially suitable for flow measurement of high viscosity oil, chemical products and ultra-pure water. It can also be connected with two temperature sensors as calorimeters. When more heat function is needed, GFM can also be used as the flow measurement part of calorimeter and connected to the calorimeter through 4-20mA as the flow measurement part.1.2 Product Features★ Flow measurement adopts double-channel ultrasonic technology to ensure measurement accuracy and stability;★ Adopt high-speed DSP processor, with response speed reaching 0.1 second;★ Advanced digital signal processing technology, the measurement is not interfered by iron filings, welding slag and other impurities;★ Different sensors can be connected to solve the problem of multi-bubble application on site1.3 Technical Indicators Technical indicatorsApplicationMeasurable liquidMost single-phase liquids.
