Ultrasonic flowmeter, reliable quality, professional service, complete specifications and models, more reasonable price. More cost-effective. Buy ultrasonic flowmeter preferred Jiangsu Shunyi Instrument Co., Ltd., Jiangsu Shunyi Instrument Engineer reported:
Hydraulic Valve Contain Main Control Valve, Pilot Valve on Pump, Relief Valve on Control Valve and Solenoid Valve.
Fuction:
(1) when the single boom is lifted, the two pumps supply oil together to improve the lifting speed of the boom. (only when the boom is raised)
(2) when the bucket rod moves separately, the two pumps supply oil to the platform and speed up the action speed of the bucket.
(3) the boom is preferred. When the boom and other actions are carried out at the same time, the action of the boom will be given priority.
(4) priority is given to rotation, and when rotary and bucket move simultaneously, gyration will be given priority.
(5) Negative flow control, to provide a negative flow signal to the main pump, so that the valve stem in the middle, the main pump displacement becomes minimum.
(6) Walking in a straight line, when the excavator is moving forward or backward, other actions can be taken at the same time to ensure the needs of special working conditions.
(7) electrical sensors can be configured to meet the needs of electronic control.
A professional manufacturer of ultrasonic flowmeters:
Ultrasonic flowmeter, reliable quality, professional service, complete specifications and models, more reasonable price. Higher cost performance. Jiangsu Shunyi Instrument Co., Ltd. is the first choice for purchasing ultrasonic flowmeters, 100% satisfactory service, ultrasonic flowmeter based on speed difference method, measurement The flow rate of the liquid in the tube, the flow rate of the fluid is proportional to the time difference between the downstream and countercurrent propagation of the ultrasonic wave. In addition, a time difference method, a frequency difference method, or the like can also be used. It has good stability and small zero drift. High measurement accuracy, wide range ratio (flow rate range: 0.01~ strong anti-interference ability, etc. It adopts advanced micro-power digital design technology such as digital transmission, digital reception, digital analysis, digital output, etc., accurate measurement, reliable operation, and more Suitable for industrial site requirements. Converters [host] are available in the form of wall-mounted converters, disk-mounted converters, and integrated converters; ultrasonic flowmeter sensors are available in the form of plug-in sensors, segment-type sensors, and external clip-on sensors. .
Second, the characteristics:
â— Micro power consumption, digital design. Using micro-power hardware and software design, digital transmission, digital reception and digital analysis of ultrasonic signals have achieved a comprehensive digital design, and the power consumption of the whole machine is less than 0.3W. The battery-powered unit consumes only 0.2mW.
â— Excellent measurement and management functions. The instrumentation uses advanced analysis and calculation techniques in software design to ensure accurate metering functions. In addition, advanced management functions have been designed, and the instruments can be used to check the instrument operation data at any time during the previous ten years.
â— Flexible maintenance performance. The reversing adaptive technology enables the series of instruments to automatically eliminate the zero error of the measurement process, and can replace the converter and sensor arbitrarily during the maintenance process without affecting the measurement accuracy.
â— Chinese character technology. The data input and measurement process of the instrument shows all Chinese characters, so that the operator can operate without using the manual.
â— Ceramic sensor, metal alloy adhesive. High strength, abrasion resistance, corrosion resistance, and not easy to scale. Particularly suitable for the measurement of high temperature, highly corrosive liquids. The use of metal adhesives, the bond is more secure, the use temperature can reach 160 degrees, especially suitable for acoustic sensors, the engineering practicality of the sensor is greatly improved.
Third, classification:
â—Insert ultrasonic flowmeter: It can be installed and maintained without stopping using our special drilling device.
