Summarization Vortex flowmeter is a flow measurement instrument based on the Karman vortex flowmeter principle, also known as vortex flowmeter or Karman vortex flowmeter. It is mainly used to measure the volume flow of gas, steam or liquid in various pipelines. It is a new type of flow meter ...
Piezoresistive pressure transmitter as below picture is characterized by its small size and simple structure. The sensitivity coefficient of diffusion resistance is dozens of times that of metal strain gauge, and can directly measure small pressure changes. In addition, piezoresistive pressure ...
The device that can detect the pressure value and provide a remote signal is collectively referred to as the pressure transmitter, which is a sensor commonly used in industrial automation process control to measure the pressure of a gas or liquid, and convert this pressure value into a measurable ...
2.4 Field configuration funetion Basic functions (no password required) 2.5 Precession flowmeter mode setting instructions 1.Gas volume (Gas Qv) A.Measure the working volume as follows Density: Set to 20'℃ density (not involved in the calculation) Pressure: 0.0KPa Temperature:20℃ B.Measure the ...
Difficulties of International Explosion-proof Certification 1. Data: All data must be translated into English, IEC or EN clauses, and each clause must be reasonably explained. The number of rectifications of data during the certification cycle far exceeds the domestic explosion-proof workload. Note: ...
In recent years, with the rapid development of China's explosion-proof technology, more and more domestic explosion-proof companies in various countries have chosen to go abroad and sell their products to countries around the world. For companies, obtaining international explosion-proof certificates ...
Selection oftemperature and pressure sampling points: (Figure 8) 1. The temperature sensor (PTl00) is cut a hole (the diameter ofthe hole is 025) after 5D downstream ofthe flow meter, weld the base, and tighten the temperature sensor. 2. The pressure transmiter takes pressure from the suction port ...
How does a Coriolis mass flow meter work? The Coriolis mass flow meter is based on the Coriolis principle. It makes the flow tube through which the medium flows vibrate. The sensor detects and analyzes the changes in the frequency, phase difference and amplitude of the flow tube, directly measures ...
Rotation flowmeter is one of the main flow meter products in the world, widely used in petroleum, chemical.metallurgical and other industrial sectors and municipal construction, environmental protection projects. The flow ofmostliquids, gases and vapors is measured, tested and controlled.Products ...
Differential pressure piping installation 1) When the measured flow body is a clean liquid, its pipeline installation diagram (as above) (2) When the measured flow body is corrosive liquid, its pipeline installation diagram (3) When the measured flow body is a clean gas, its pipeline installation ...
When the fluid filled with pipes flows through the throttling parts (orificles, nozzles, etc.) in the pipes, the fluid will form a local contraction at the throttling parts, so that the flow rate increases and the static pressure decreases, so that the pressure drop or pressure difference is ...
Tuning fork liquid level switch is a type of liquid level control switch. The tuning fork is excited by the crystal to generate vibration. When the tuning fork is immersed in liquid, the vibration frequency changes, and the frequency change is detected by the electronic circuit and outputs a switch ...
