Insertion flow meter

Because all kinds of ultrasonic flowmeters can be installed outside the pipe, non-contact flow measurement, the cost of the instrument is basically independent of the size of the pipe to be tested, while other types of flowmeters increase with the increase in caliber, so the cost is increased. The flowmeter is superior to the other functions of the same type of flowmeter. It is considered to be a good large-diameter flow measuring instrument. The Doppler ultrasonic flowmeter can measure the flow of two-phase medium, so it can be used for the measurement of dirty sewage such as sewers and sewage. In power plants, the use of portable ultrasonic flowmeters to measure large pipe diameters such as turbine water inflow and turbine circulating water is much more convenient than in the past. Ultrasonic flow juice can also be used for gas measurement. Pipe diameters range from 2cm to 5m, from a few meters wide open channels, culverts to 500m wide rivers.
In addition, the accuracy of the flow measurement of the ultrasonic measuring instrument is almost independent of the temperature, pressure, viscosity, density and other parameters of the measured fluid, and can be made into non-contact and portable measuring instruments, so it can solve the problem that other types of instruments are difficult to measure. Flow measurement problems for corrosive, non-conductive, radioactive, and flammable and explosive media. In addition, in view of the non-contact measurement characteristics, coupled with reasonable electronic circuits, one instrument can adapt to a variety of pipe diameter measurements and a variety of flow range measurements. The adaptability of ultrasonic flowmeters is also unmatched by other instruments. Ultrasonic flowmeters have some of the above advantages, so it has received more and more attention and has been developed into a series of products and generalization. It has been made into standard, high-temperature, explosion-proof and wet instruments of different channels to adapt to different media. Flow measurement for occasions and different pipeline conditions.

Product advantage and preservation
The vortex flowmeter adopts micro-power high-tech, and can be operated continuously by lithium battery for more than one year, which saves the purchase and installation cost of cables and display instruments, and can display instantaneous flow and accumulated flow on the spot. The temperature-compensated integrated vortex flowmeter also has a temperature sensor that directly measures the temperature of the saturated steam and calculates the pressure to show the mass flow of the saturated steam. The temperature and pressure compensation integrated type has a temperature and pressure sensor. The gas flow measurement can directly measure the temperature and pressure of the gas medium, thereby indicating the volumetric volume flow of the gas.
In order to prevent accidental damage to the instrument, please keep the packaging status of our company when it is shipped to the user.
After the instrument arrives, it should be installed in time to avoid the insulation performance of the flow converter being reduced due to unexpected factors, and the metal parts are corroded. If you need to store for a long time, please observe the following:
1. When storing, try not to unpack.
2. The storage location should have the following conditions:
3. With rainproof and waterproof facilities
4. Not susceptible to mechanical vibration or shock
5. The instrument should be stored in the temperature and humidity ranges listed in the table below. The ideal temperature and humidity is 25 ° C, 65%
6. Ambient temperature -20 ° C ~ +60 ° C
7. Relative humidity 5% to 90%

Flow meter type

Instruments that measure fluid flow are collectively referred to as flow meters or flow meters. The flowmeter is one of the important instruments in industrial measurement. With the development of industrial production, the accuracy and range of flow measurement requirements are getting higher and higher, and the flow measurement technology is changing with each passing day. Various types of flow meters have been introduced to suit various applications. More than 100 flow meters have been put into use. From different perspectives, flow meters have different classification methods. There are two commonly used classification methods. One is to classify according to the measurement principle adopted by the flowmeter: the second is to classify according to the structural principle of the flowmeter.
Classified by flowmeter structure principle
Volumetric flowmeter
A volumetric flow meter is equivalent to a standard volume container that measures the flow medium continuously. The larger the traffic, the more times the metric is, and the higher the frequency of the output. The principle of the volumetric flowmeter is relatively simple and suitable for measuring fluids with high viscosity and low Reynolds number. According to the shape of the rotary body, the products currently produced are: an oval gear flow meter suitable for measuring liquid flow, a lumbar flowmeter (Roots flowmeter), a rotary piston and a scraper flowmeter; a servo type suitable for measuring gas flow Volumetric flowmeters, membranes and flowmeters, etc.
