1. Use a V-cone flowmeter to measure the natural gas flow rate, and the output signal is a differential pressure signal without square root. The V-cone flow rate can be found on Baidu Suggestion:
1. Perform square root operation on the differential pressure signal to obtain the flow percentage, and then multiply it by the flow upper limit to obtain the instantaneous flow rate.

2、 The temperature and pressure compensation calculation for the flow rate during transient dry burial is the required result. The differential pressure value provided by the manufacturer is based on the calculation formula of the product, so knowing the differential pressure can obtain the flow rate. Calculating the flow rate according to the above method is actually just the inverse calculation of the formula. In addition, the pressure loss of micro cone flow meters is still relatively large. It is recommended that similar applications can use a averaging tube flow meter (such as a delta flowmeter). The pressure loss is almost negligible, which has a good energy-saving effect and is particularly easy to install and maintain.

2. How to measure the flow rate of natural gas pipelines and hot air pipelines in tunnel kilns The flow rates of natural gas and hot air pipelines in tunnel kilns can be measured using a V-cone flowmeter with a ruler. It is a gas flow measurement instrument that can be used to measure the flow rates of these two gases.

To solve the problem of measuring natural gas flow in kilns, a V-cone flowmeter can be used. Natural gas and hot air, as the main gases for kiln combusti

on, can only achieve their best efficiency when the ratio reaches 1:10. Therefore, a V-cone flowmeter can be used to measure natural gas and hot air flow measurement problems. What is a V-cone flowmeter? The conical shape of the V-cone disperses fluid flow, resulting in a flatter velocity distribution. The pointed cone itself is a flow regulator that can effectively reduce the convex shape in velocity distribution. Make the fluid velocity distribution conform to the requirements of dust and dirt, effectively reduce the requirement for upstream straight pipes, lower installation costs, suitable for most gas, fluid, and steam applications, as well as high temperature and high pressure applications, easy to use, inspect, and troubleshoot. The main advantage of V-cone flowmeter is that it has a small permanent pressure loss, forming a unique local contraction. The permanent pressure loss is small, only a few thousand pascals, or even a few thousand pascals at zero. The cone causes the fluid axis to gradually contract towards the pipe wall symmetrically, and the gradually diffusing side walls are throttled. The cone is located on the central axis of the pipeline and effectively acts on the high-speed central area. Under the same conditions, the permanent pressure loss of the V-cone is 25% of the orifice plate, and the differential pressure is 50% of the orifice plate, resulting in low energy consumption.

2、 The accuracy is 0.5% high, the repeatability is good at 0.1%, and the range ratio is 10:1. Due to the "inner wall gradually contracting" throttling method used by the V-cone flow sensor, the static pressure generated on the downstream side is a high-frequency low amplitude signal (surge flow), rather than a low-freq
