Xiamen Jingchuan Micro Flow Mass Flow MeterCore technological advantages
DN1 small pipe diameter accurately adapts to small pipelinesUsing precision machined DN1 micro measuring tubes, it can seamlessly connect to DN1 micro pipelines of laboratory micro injection pumps, environmental monitoring sampling devices, micro reaction vessels and other equipment without the need for diameter modification of existing pipelines, with strong adaptability. The inner wall of the measuring tube is polished with a mirror finish and treated with a PTFE coating to reduce fluid adhesion and retention. Even high viscosity colloids, volatile organic solvents, or corrosive reagents can quickly pass through and be accurately measured. In the analysis of trace pollutants in environmental water quality, the sampling pipeline can be directly connected to avoid sample loss or measurement deviation caused by mismatched pipeline diameters, ensuring the authenticity and reliability of monitoring data.
High precision measurement in small flow intervalsBased on the principle of Coriolis effect, the mass flow rate of the fluid is directly measured by detecting the inertial force generated by the fluid flowing in the vibrating tube, and the results are not affected by changes in parameters such as temperature, pressure, viscosity, etc. Specially optimized for the small flow range of 0.001-1kg/h, the measurement error is strictly controlled within ± 0.1%, and the repeatability reaches ± 0.05%. Whether it is a low viscosity environmental protection detection reagent or a high viscosity pharmaceutical gel, it can stably capture the slight fluctuation of flow, solve the problem of "metering blind area" of traditional flowmeter in the scene of small flow and small pipe diameter, and provide accurate data support for cost accounting and process optimization of high-value materials.
Resistant to complex media and harsh environmentsBased on the fluid characteristics of different industries, the flowmeter body is made of Hastelloy C276 and Sapphire composite material, which is formed by integral forging process and has corrosion resistance increased by more than 30% compared to traditional materials. The internal vibration tube is sealed by laser welding and equipped with a nano level wear-resistant coating, which can resist the erosion of corrosive media such as acid and alkali solutions and organic solvents, as well as the scouring of small particles in the fluid. The working temperature range covers -40 ℃ -200 ℃, with a maximum pressure of 10MPa, and can still maintain stable operation under high temperature and high pressure conditions; The protection level reaches IP67, which can adapt to humid and dusty laboratory and industrial site environments, with an average time of over 10000 hours.
Intelligent data management and linkage controlBuilt in high-performance microprocessor, supporting 4-20mA analog signals, RS485 digital signals, and Modbus protocol output, can seamlessly integrate with PLC systems, laboratory data acquisition platforms, and environmental monitoring terminals. Equipped with real-time flow monitoring, historical data storage (with a capacity of up to 12 months), and trend analysis functions, it can automatically generate flow statistics reports to help users intuitively grasp fluid consumption patterns. When abnormal flow fluctuations are detected, sound and light alarms can be triggered and valve adjustments can be linked to prevent excessive material consumption or pipeline blockage; Supporting remote operation and maintenance, parameter calibration and fault diagnosis can be completed through a mobile app, significantly reducing labor costs.

Working principle of mass flowmeterOther precautions during sensor installation process
2.4.1 New pipeline needs to be purged
For newly built pipelines, sensors should be installed after completing pipeline pre installation and pipeline blowing to avoid accidental damage to sensors caused by pipeline construction and to prevent debris from entering the sensors. The handling equipment for instruments should be operated reliably, with light lifting and handling, and dropping and bumping can easily cause sensor damage.
2.4.2 Appearance inspection before installation
Before installing the sensor, please carefully inspect the product packaging, sensor housing, and transmitter housing for any obvious deformations, scratches, water immersion marks, or other abnormal conditions. If the above issues exist, please communicate with the carrier and supplier for confirmation. Ensure that the installation environment of the flowmeter meets the explosion-proof level requirements of the flowmeter.
2.4.3 Coaxial installation
Jingchuan DN1 mass flowmeter can measure 100g per hourThe diameter of the sensor installation interface must be coaxially connected to the diameter of the pipeline interface in order to reduce installation requirements
Strength ensures measurement error. During installation, the flanges on both sides should be parallel and the process pipeline should be supported by pipeline supports. It is prohibited to use sensors to support the process pipeline. The sensor housing should be kept suspended and not in contact with any object.
2.4.4High precision quality flowmeterDuring installation, there should be stable support near the flange of the process pipeline on both sides (approximately 2-10 times the diameter). When on the process pipeline, it is necessary to ensure that the pipeline system is firmly connected to two stable supports on the upstream and downstream sides of the sensor. All threaded connections must be tightened, and clamping the process pipeline can help reduce potential vibration interference. If there is significant vibration in the process pipeline, please choose to connect the elastic corrugated pipe with the sensor flange to avoid the transmission of pipeline vibration to the sensor measuring pipe through the flange, which may affect measurement error and stability.
