1.2025 Recommended Brands and Selection Suggestions for Solid Flowmeters

Recommended Brands and Selection Suggestions for Solid Flowmeters in 2025 are as follows:

1. Recommended Brands and Products Shijiazhuang Dongya Electronic Technology Co., Ltd. Recommended Product: GTL-A Solid Flowmeter Technical Principle: Based on the theory of solid material contact electrification, flow measurement is achieved by capturing the signal of charged powder particles and converting it into a standard current signal (4-20mA). Product features: Customizable range, supporting multiple application scenarios (such as coal injection for power plant boilers, pneumatic conveying of limestone powder, blast furnace coal injection, etc.). Through CAP certification and national explosion-proof certification, it has high safety. The output signal is linearly related to the powder flow rate and can be directly converted to mass flow rate (kg/H or T/H). Applicable scenarios: Powder flow monitoring that requires high precision and explosion-proof requirements, such as chemical, power, environmental protection and other industries. Schenck Process (Germany) recommends product: Impact solid flow meter. Technical principle: By measuring the force generated by the impact of the falling material on the detection plate, the mass flow rate is calculated. Product features: High precision, strong stability, excellent anti-interference ability, suitable for long-term continuous operation. The material is wear-resistant and suitable for highly abrasive materials such as cement and mineral powder. Applicable scenarios: Cement, mining, power and other industries, used for measuring powdery or fine-grained materials from silos to conveying equipme

nt (such as belt scales, screw pumps). Siemens recommended product: SITRANS FC series solid flow meter. Technical principle: using electrostatic induction or capacitance principle, flow measurement is achieved by detecting the electrostatic charge or capacitance change generated by material friction. Product features: Non invasive design with minimal impact on the flow field of pneumatic conveying pipelines. Suitable for materials with low conductivity or changes in dielectric constant, such as flour and plastic particles. Applicable scenarios: Measurement of powder mass flow rate in pneumatic conveying pipelines, such as power plant fly ash and cement conveying. Secondly, it is recommended to carefully choose the technical principle of free fall/gravity feeding scenario based on the installation location and method (such as feeding through a rotary valve in a silo): priority should be given to flow meters based on the impact plate principle (such as Shenke products), as they directly measure the impact force of materials, have high accuracy, and strong anti-interference ability. Scenario of pneumatic conveying pipeline draft (such as horizontal or inclined conveying): Choose flow meters based on electrostatic/capacitive principles (such as Siemens SITRANS FC series) or microwave principles to avoid interference with the flow field caused by invasive design. Consider the influence of material characteristics on selection. Physical properties: Particle size: Fine powder materials (such as coal powder) are suitable for the principle of electrostatic induction; Coarse particle materials (such as mineral powder) should be selected using impact plates with strong wear resistance. Humidity and adhesion: High humidity or easily
