1. Is the Cologne flowmeter a joint venture brand?

2. What are the characteristics of the metal tube float flowmeter? The working principle of the metal tube float flowmeter.

The measurement principle of the Chengde Wanji WJ series metal tube float stove flowmeter is that the measuring component consists of a conical measuring tube and a float. The float can move freely up and down in the conical measuring tube, changing the flow area in the pipeline. As the flow rate changes, the vertical ignition position of the float in the measuring tube also changes accordingly. The position of the float is transmitted to the indicator dial through a magnetic transmission system, indicating the flow value on site. It can also output signals for remote display and control.

1、 Suitable for flow measurement of small caliber and low velocity media.

2、 Modular combination design, easy to maintain, and maintenance free for normal use.

3、 Single axis sensitive indication, non-contact new magnetic coupling structure, more stable signal transmission.

4、 Dual row, large screen LCD display for instantaneous and cumulative traffic, with backlight capability.

5、 The intelligent model has power failure protection, data backup and recovery functions.

6、 All metal structure, earthquake resistant, pressure resistant, temperature resistant, anti-corrosion, long service life.

7、 The requirements for straight pipe sections are relatively low.

8、 Can be used in flammable and explosive hazardous environments.

9、 Three power supply modes are available: DC24V, AC220V, and battery power supply.

3. How to calibrate a flowmeter? In practical use, if the temperature, pressure, and properties of the medium are different from the calibration time, or if the flow meter wears out significantly after long-term use, or if a non-standard flow meter is manufactured by oneself, it is necessary to calibrate the flow meter and re determine its flow coefficient or calibration curve. The calibration methods for flow meters include volume method, weighing method, standard flowmeter method, etc. Each flowmeter undergoes strict calibration and testing before leaving the factory. However, due to changes in the environment and differences in installation conditions during use, especially in the potato mold conditions where the measured medium is significantly different from the original calibration medium, the flowmeter may have corresponding indication errors during the measurement process. If it is damaged, it needs to be re calibrated. Additional information: Flow measurement is widely used in various fields such as industrial and agricultural production, national defense construction, scientific research, foreign trade, and peoples daily lives. In the production of the petroleum industry, flow measurement runs through the entire process from oil extraction, transportation, refining and processing to trade and sales. Any link cannot be separated from flow measurement, otherwise the normal production and trade exchanges of the petroleum industry cannot be guaranteed. In the chemical industry, inaccurate flow measurement can cause an imbalance in the distribution ratio of chemical components, which cannot guarantee product quality and can even lead to production safety accidents. The measurement and regulation of the flow rate of liquid, gas, steam and other media play an important role in the production
