Key points for selecting flow meters

2025-08-06

Measurement requirements: Select the appropriate type of flowmeter based on measurement accuracy requirements. Fluid characteristics: Consider the influence of fluid viscosity, density, temperature, pressure, and other characteristics on measurement results. For example, high viscosity fluids may not be suitable for using turbine flow meters or electromagnetic flow meters; Fluids containing solid particles may clog certain types of flow meters. Installation conditions: Select the appropriate type and installation method of flowmeter according to the installation environment. For example, in situations where non-contact measurement is required, ultrasonic flow meters can be chosen; In situations where space is limited, compact flow meters can be chosen. Economic factors: Considering the cost and maintenance expenses of the flowmeter while meeting measurement needs. The prices of different types and brands of flow meters vary greatly, and it is necessary to choose according to actual needs....

Technical principle of pressure transmitter

2025-08-06

A pressure transmitter is an industrial automation instrument that converts pressure signals into standard electrical signals (such as 4-20mA DC, 0-10V DC, or digital signals). Its technical principles can be summarized into four core links: pressure sensing, signal conversion, signal amplification and processing, output and transmission, as follows: 1、 Pressure sensing The core of a pressure transmitter is the sensor, which is responsible for directly sensing changes in external pressure. Common types of sensors include: Piezoresistive sensor: utilizing the piezoresistive effect of semiconductor or metal materials. When pressure is applied to the sensor diaphragm, the diaphragm undergoes deformation, causing a change in the internal resistance value. Convert resistance changes into voltage signals through a Wheatstone bridge. Capacitive sensor: composed of two parallel electrode plates. Pressure causes a change in the capacitance value between the diaphragm electrode and the fixed electrode, which is then converted into an electrical signal. Piezoelectric sensor: Utilizing the characteristic of piezoelectric materials (such as quartz crystals) generating charges under pressure, it outputs an electrical signal proportional to the pressure. This type of sensor is suitable for dynamic pressure me...

The core advantages of infrared gas leak detector

2025-08-06

The core advantages of infrared gas leak detectors are reflected in five aspects: non-contact remote detection, high-sensitivity visual positioning, efficient safety inspection, anti-interference adaptation to complex working conditions, quantitative leakage and preventive maintenance. The specific analysis is as follows: 1、Non contact and long-distance detection capability Infrared gas leak detectors can detect leaks from tens to hundreds of meters away, without the need to be close to high-pressure, high-temperature, or toxic gas areas (such as high-altitude pipelines and chemical plant reactors). For example, the Hanwei R10 handheld detector can detect distances up to 20 meters, and the T-800 airborne system can achieve large-scale rapid screening through unmanned aerial vehicles, avoiding direct contact with hazardous environments and significantly improving safety. 2、High sensitivity and visual positioning The device can detect trace leaks at PPB level (one billionth) or PPM level (one millionth), and visually display the gas plume morphology and diffusion direction through thermal imaging. For example, the LUFT300 VOC gas infrared leak detector uses a type II superlattice cooling detector, which can locate small VOC leakage points in real time; The Fujirui infrared leak detector uses a 320...
