What is the installation size of DN80 flange for orifice flowmeter?

1. The outer diameter of the flange is 200 millimeters, ensuring that it matches the flange of the orifice flowmeter

2. The distance between the flange centerlines is set to 160 millimeters for the correct installation of the orifice flowmeter

3. The diameter of the straight field of the bolt is specified as 18 millimeters, which ensures sufficient fastening force and is suitable for the standard size of the flowmeter

4. The number of bolt holes is 8, evenly distributed according to the standard layout to meet the flange connection requirements of the flowmeter.

2. What is the difference between flange type and clamp type vortex flowmeter?

Vortex flowmeter clamping type refers to the situation where the flowmeter body does not have a flange, the pipeline has a flange, and the pipeline is tightened with bolts to firmly clamp the flowmeter inside, so it is called clamping.. The flange type has flanges on both the body and the pipeline, and is fixed and installed by a pair of flanges, so the clamping pressure and diameter are not high. But Jie Xiang secretly arranged for 2 flanges, which can be cheaper or much lighter for transporting dry goods.

3. How to check the flange weight and diameter of the flowmeter

The model, diameter, and flange weight of the flowmeter are key information that needs to be paid attention to when selecting and installing a flowmeter.

. On the technical specification sheet or nameplate of the flowmeter, this information is usually clearly listed. For example, the Q400 model flow meter has a diameter of DN100 and a flange weight of CLASS150, indicating th Flanges and flow meters

at the flow meter can withstand a pressure rating of 150 pounds force per square inch of the stove. The caliber DN100 refers to the inner diameter of the flowmeter pipeline, and DN is the abbreviation of the German word "Durchmesser Nummer", which is the nominal diameter. Here, 100 represents the size of the inner diameter of the pipeline, which is 100 millimeters. The selection of caliber needs to be determined based on the actual fluid flow requirements to ensure that the flowmeter can accurately measure the fluid flow rate. The flange weight CLASS150 indicates the pressure bearing capacity of the flowmeter flange. CLASS150 means that the flange can withstand a maximum working pressure of 150 pounds force per square inch (psi), typically used in medium pressure piping systems. When selecting a flowmeter, the flange weight needs to match the design pressure of the pipeline system to ensure safe operation of the system. In practical applications, it is also necessary to pay attention to factors such as the pressure rating, temperature range, and material of the flowmeter. For example, if the working pressure of the pipeline system exceeds 150 pounds force per square inch, it is necessary to choose a higher class flange, such as a CLASS300 or CLASS600 flowmeter. In short, selecting a suitable flowmeter requires comprehensive consideration of the flowmeter model, diameter, flange weight, and specific requirements of the pipeline system. By carefully examining the technical specifications of the flowmeter, it can be ensured that the selected flowmeter meets the actual needs of the system, thereby ensuring the accuracy of measurement and the safety of the system.
