The vortex flowmeter is charged according to the pipe diameter, and the larger the more, the more expensive. And different manufacturers are very different, so you have to compare and then bargain. As for the selection, the model is selected according to the working environment of the site and the nature of the medium to be measured.

You buy a manufacturer's product, and the other party can calculate it with you. I can't just say that, I don't understand. There are many parameters to know, such as what medium is being measured and the pressure of the pipe.

Temperature, density, and long-term flow, maximum flow, minimum flow and other parameters to calculate and then select, flowmeter to have temperature, pressure and other compensation Variable diameter is very common. There is no big difference in the vortex street technology made in China. The craftsmanship is very mature.

We all choose manufacturers close to ourselves to buy. Easy access and calibration. If there is any problem, a ** manufacturer will come to someone.

Easy to change. You can send some parameters of your site to help you choose.

The caliber of the vortex flowmeter is to be selected according to the measurement medium, flow range and other parameters, I bought the vortex flowmeter in Shanghai Fanyang Electromechanical ****, consult them to help me choose the model, their selection is very professional, ** is quite advantageous, the quality is very stable with it, you can consult 021-51696800

Heshunda vortex flowmeter is mainly used for flow measurement of industrial pipeline medium fluids, such as gas, liquid, vapor and other media.

It is characterized by small pressure loss, large measuring range, high accuracy, and is almost not affected by fluid density, pressure, temperature, viscosity and other parameters when measuring the volume flow under working conditions.

Professional instrument manufacturer.

Heshunda vortex flowmeter can measure the flow rate of steam and gas with low viscosity liquids.

The biggest advantage is that the gauge coefficient is not affected by the physical properties of the measurement medium and can be generalized from one typical medium to other media. However, due to the large difference in the flow velocity range of liquid and gas, the frequency range is also very different. In the amplifier circuit that processes the vortex signal, the passband of the filter is different, and the circuit parameters are also different, so the same circuit parameter cannot be used to measure different media.

If you need to buy, you will generally need to provide the properties of the medium for the merchant to judge, and may also provide temperature, pressure and flow ranges.

As for the parameters you want to ask, it should be the installation method, output method and accuracy.

Hehe, Jiang Zhongxia is the director of the flow room of my original unit (Chongqing Industrial Automation Instrument Research Institute). The vortex flowmeter was first introduced to Japan because I learned Japanese, and I translated some of the initial materials. However, now these people don't know that they are in **.

The vortex flowmeter is very simple, it is to insert a metal rod into the pipe, because the metal rod changes the fluid distribution, a vortex is generated, and the vortex can be measured with an ultrasonic sensor to measure its frequency, and the size of the flow rate is known. Now there are many of them, and some of them are called vortex flowmeters.

I have used a lot of domestic flowmeters are similar, it is recommended to choose joint venture products, ** is more reasonable, the product performance is also stable, EJA, Virvo effect is good, after-sales is also guaranteed.

The quality of domestic products is almost the same, and it is best to find a good strength and after-sales guarantee.

Qingtian Instrument Technology **** Yes, I heard that the strength is also good!

Some domestic manufacturers are directly OEM, and some buy parts to assemble, the quality is not guaranteed, want to buy domestic to find a company with their own development and production capacity, after-sales to keep up.

Shaanxi Weinan and Shunda is a modern instrument, CNC equipment manufacturer. From the early days of its establishment, the company has formulated a development direction of arming itself with advanced technology, a high starting point and high specifications, close to the market and customers, and providing users with a series of products such as gas flowmeter, target flowmeter, heavy oil flowmeter, high temperature flowmeter, chlorine flowmeter and so on with the concept of "rigorous, pragmatic and innovative".

In practical application, often the maximum flow rate is far lower than the upper limit value of the instrument, with the change of load, the minimum flow rate is often lower than the lower limit value of the instrument, the instrument does not work in its best working section, in order to solve this problem, usually adopt the flow rate of the measurement place by reducing the diameter at the measurement place, and select the instrument of smaller diameter to facilitate the measurement of the instrument, but this reducer mode must have a straight pipe section with a length of more than 15d between the reducer and the instrument for rectification, so that the processing and installation are inconvenient. The LGZ variable diameter rectifier developed by our company with a circular cross-sectional shape has multiple functions of rectification, increasing the flow rate and changing the flow rate distribution, and its structure size is small, only 1 3 of the inner diameter of the process pipe, and the vortex flowmeter is integrated, not only does not need to attach a section of straight pipe section, but also can reduce the requirements for the straight pipe section of the process pipe, and the installation is very convenient.

In order to be easy to use, the battery-powered local display vortex flowmeter adopts micro-power high-tech, and can run uninterrupted for more than one year with lithium battery power supply, which saves the purchase and installation cost of cables and display meters, and can display instantaneous flow and cumulative flow on the spot. The temperature-compensated vortex flowmeter also has a temperature sensor that can directly measure the temperature of the saturated steam and calculate the pressure to display the mass flow rate of the saturated steam. The integrated type of temperature and pressure compensation is equipped with temperature and pressure sensors for gas flow measurement, which can directly measure the temperature and pressure of the gas medium, so as to display the standard volume flow rate of the gas.

By detecting the temperature and pressure in time, the changing density is calculated and compensated accordingly.
