Solid speed meter (capacitance-based)

1. Product Function
1, pulverized coal gasifier pipeline pulverized coal flow measurement, involved in measurement, control and interlocking;
2, pulverized coal injection system pulverized coal flow measurement;


2.Product Features
1, excellent original signal amplification processing (adaptive amplification) technology to make the device more suitable for the production of a wide range of operating conditions, the density range of 60mg / cm3 ~ 890mg / cm3, the maximum to avoid measuring results zero, disorderly fluctuations Phenomenon, to ensure that the measurement results accurate, stable and reliable;
2, within the scope of the determined density conditions, the equipment is used directly, without any adjustment and correction;
3, with advanced correlation and stability of the algorithm, the measurement results accurate, stable and reliable;
4, high wear-resistant, high-strength structural design, unique circuit design and selection of electronic components, has good high temperature performance and resistance to environmental corrosion, to ensure the safety and life of equipment.
5, assembly-type lining design, easy to replace the liner, significantly reduce customer maintenance costs later;

3. System Composition
System consists of two parts, namely, the host and sensor
(A) host (single wall-mounted)


(B) host (plug-in box, a rack of four hosts, a single host two signal output)


(C) Sensor
