ltrasonic flowmeter installation
The time difference ultrasonic flowmeter is a competitive flow measurement method in the world today, and its measurement line accuracy is higher than 1.0%. Due to the diversity of the industrial site, especially the environment around the pipeline, how to install and debug the ultrasonic flowmeter according to the specific environment has become an important topic in the field of ultrasonic flow measurement. This procedure explains the installation details of the ultrasonic flowmeter; It further fully demonstrates the advantages of accuracy, reliability and stability of the ultrasonic flowmeter, greatly reducing future maintenance work and even maintenance-free.
Ultrasonic flowmeters should be aware of the site prior to installation, including:
1. What is the distance from the host at the installation of the sensor;
2. Pipe material, pipe wall thickness and pipe diameter;
3. Year of the pipeline;
4. Type of fluid, whether it contains impurities, bubbles, and whether it is full;
5. Fluid temperature
6. Whether there is interference source at the installation site (such as frequency conversion, strong magnetic field, etc.);
7. The temperature of the four seasons at the host site;
8. Whether the power supply voltage used is stable;
9. Whether remote signals and types are required;
According to the site conditions provided above, the manufacturer can configure the site conditions and, if necessary, special models.
Intelligent GPRS MAG flow meter
The GPRS wireless transmission flowmeter is specially designed for the industry. It can meet the monitoring and management of traffic in urban water supply, heating and gas supply systems, and the processing and calculation of data. It is widely used in urban water supply, heating, gas supply systems, sewage treatment, Water conservancy projects and other industries.
GPRS wireless transmission flowmeter battery-powered converter is to use GPRS wireless communication to achieve remote monitoring. The data of the battery-powered converter can be read in any area covered by the GPRS wireless network. Through the GPRS wireless communication flowmeter network system, the data collected by the field instrument can be transmitted to the monitoring center in real time to achieve unified monitoring and distributed management of the field instrument.
GPRS wireless transmission flowmeter adopts specially designed sensor excitation system and high-performance lithium battery power supply system, and adopts 16-bit embedded ultra-micro power processor, full digital signal processing, stable measurement, high measurement accuracy and strong anti-interference ability. Features such as automatic bidirectional flow measurement, on-site instantaneous flow, positive and negativecumulative total display, self-diagnosis fault alarm, GSM data infinity transfer, etc. Users can realize traffic data through powerful GSM/GPRS remote management software system. GPRS wireless communication, storage, data analysis and other functions.
Turbine flow meter applications
Turbine flow meters are widely used in the following measurement objects: petroleum, organic liquids, inorganic liquids, liquefied gases, natural gas, gas and cryogenic fluids. In the transshipment and gathering stations of foreign liquefied petroleum gas, refined oil and light crude oil, the first and last stations of large crude oil transmission pipelines use it for trade settlement. In Europe and the United States, the turbine flowmeter is the natural gas meter next to the orifice flowmeter. In the Netherlands alone, more than 2,600 gas turbine flowmeters of various sizes and pressures from 0.8 MPa to 6.5 MPa are used on the natural gas pipeline. Has become an excellent natural gas flow meter. Although the excellent metering characteristics of the turbine flow meter are favored by people, the impression is that the moving parts are short in use time, and they are inevitable in the selection. After people's unremitting efforts, it should be said that the situation has changed a lot. As the most versatile flowmeter, the turbine flowmeter has been developed into a multi-variety, full-series, multi-size mass production scale.
