What are the sizes corresponding to different diameters of vortex flowmeters?

Vortex flowmeters of different diameters correspond to different sizes, and products produced by different manufacturers may have differences in specific dimensions. Taking the common DN25 caliber as an example, its length is generally around 150mm and the outer diameter is about 32mm. The DN50 caliber vortex flow meter has a length of about 200mm and an outer diameter of about 57mm. For DN80 caliber, the length is usually around 250mm and the outer diameter is about 89mm. For DN100 caliber, the length is about 300mm and the outer diameter is about 108mm. When the caliber increases to DN150, the length is approximately 400mm and the outer diameter is about 159mm. The length of a DN200 caliber vortex flowmeter is generally around 500mm and the outer diameter is about 219mm. These dimensional data are only approximate ranges. In practical applications, when selecting a vortex flowmeter, accurate dimensional information should be obtained based on the product manual and specification parameter table provided by the specific manufacturer to ensure correct installation and use.

2. What do the two probes up and DN represent for ultrasonic flowmeter?

Ultrasonic flowmeter is an instrument used to measure the flow rate of liquids or gases.

. It measures the velocity and flow rate of fluids by emitting ultrasonic waves. In the ultrasonic flow slag meter, there are two probes, namely the up and DN probes. What do these two probes represent respectively? Up probe refers to an upstream probe, usually installed at the upstream position of a fluid pipeline. It is mainly used to measure the velocity and flow rate of fluids, and tr

ansmit the data to the processor of the lumens meter. The function of the up probe is to measure the velocity and flow rate of the fluid by emitting ultrasonic waves, and then transmit the data to the processor of the flow meter for processing and analysis. DN probe refers to a downstream probe, usually installed in the downstream position of a fluid pipeline. It is mainly used to receive ultrasonic signals emitted by the up probe and convert them into electrical signals, and then transmit the data to the processor of the flow meter. The function of the DN probe is to receive the ultrasonic signal emitted by the up probe, convert it into an electrical signal, and then transmit the data to the processor of the flow meter for processing and analysis. In short, both the up probe and DN probe are very important components in ultrasonic flow meters. They respectively represent the upstream and downstream positions of the fluid pipeline, and measure the velocity and flow rate of the fluid by emitting and receiving ultrasonic signals, thereby achieving accurate measurement and control of fluid flow rate.

3. What are the measurement ranges of electromagnetic flow meters?

1、 Electromagnetic flowmeter is a very sensitive flowmeter that can measure the flow rate of conductive liquids. It is also economical and has a diameter of generally DN10-- DN2000. It can measure sewage or corrosive liquids and has a wide range of applications;

2、 Electromagnetic flow meters can only measure volumetric flow rates, with units such as m3/h (cubic meters/hour), L/min (liters/minute), etc. They have pure grinding instantaneous flow rate display and cumulative flow rate display;

3、 The measurement range c
