1.Coriolis mass flowmeter There are two types of mass flow measurement: direct (direct measurement of fluid mass flow) and indirect (measurement of mass flow through a combination of volume flowmeters and densitometers). Coriolis mass flowmeters are direct type. 2. Working principle The fluid enters ...
The measurement interface of guided wave radar is based on the difference in dielectric constant of the medium and the principle of electromagnetic wave reflection. 1. Electromagnetic wave reflection mechanism: The electromagnetic waves emitted by guided wave radar will partially reflect when ...
How does the liquid thermal mass Flow Sensor work? Thermal mass flow sensors use the thermal characteristics of a liquid to measure its mass flow. As shown in Figure 1, heat is introduced into the flowing liquid through a heater, and the (temperature) sensor measures how much heat is absorbed by the ...
The principle of differential pressure transmitter for flow measurement is based on Bernoulli equation and differential pressure-flow relationship in fluid mechanics. Principle statement Differential pressure transmitters calculate flow by measuring the difference in pressure produced by a fluid ...
Shaanxi Nuoying Automation Instrument Co., Ltd. is an enterprise integrating research, design, production and sales of level instruments. It is a high-tech entity that has grown up relying on the intensive high-tech talents and strong technical force of Xi 'an University of Posts and Telecommunicati...
There are five common signal output types for sensors in level switches: relay output, two-wire output, transistor output, contactless output and NAMUR output. Among them, relay output is the most widely used, transistor output and contactless output are rarely involved, and two-wire output and ...
Intro The air separation unit is a supporting project of public works, providing nitrogen, oxygen and argon for construction for each unit, power station and auxiliary facilities. The main product of nitrogen is used for purging, sealing, displacement and security. The air cooling tower is an air ...
Working principle： When the fluid flows through the orifice plate of the orifice plate flow meter device, the cross-sectional area decreases, the velocity increases, and the corresponding pressure decreases, and the degree of reduction is proportional to the fluid velocity of the flow state. ...
Ultrasonic level meter is widely used for level measurement in chemical industry, water treatment, water conservancy, food, grain and other industries. The product has the characteristics of safety, cleanliness, high precision, long life, stability and reliability, easy installation and maintenance, ...
Fault category: Hardware failure Operating conditions: The liquid level display suddenly fluctuates several times, and the display returns to normal after zero correction. Fault symptom description: During the process control and monitoring panel, it was found that the liquid level display of the ...
Fault category: The liquid level indication is inaccurate and fluctuating Operating conditions: Measure the depth of the liquid level of the initial rainwater tank (usually the main medium is road rain and steam drizzle), normal temperature, normal pressure, and atmospheric exposure. When the liquid ...
Working principle The switch structure of float level controller is mainly designed and produced based on the principle of buoyancy and static magnetic field. The position of float ball with magnet (referred to as float ball) in the measured medium is affected by buoyancy. In the place of use, the ...
