German Kracht flowmeter

The Kracht flowmeter from Germany is a device used to measure the flow rate of liquids or gases. It adopts * sensing technology and precise measurement principles, which can monitor the volume or mass flow rate of fluids in real time and output corresponding digital signals or other forms of display results.

Kracht is a well-known flowmeter manufacturer in Germany. They focus on designing and producing high-quality, high-precision flow measurement instruments. The German Kracht flowmeter includes various types such as turbine flowmeter, liquid flowmeter, and gas flowmeter, which can be widely used in industrial automation, aerospace, energy and other fields.

　　1、 Accuracy characteristics of German Kracht flowmeter VC0.1F1PS:

1. The precision data involved in KRACHT refers to the geometric tooth product Vgz, which is the percentage offset corresponding to the current value in each case.

2. The linear error of the entire measurement range is less than ± 0.1%

3. The repeatability of the measured values is less than 0.1%

4. Accuracy testing is a part of quality inspection in various situations.

5. The test results can be recorded in the form of precision characteristic curves according to requirements; The following are examples related to Series 1 VC 1.

6. The accuracy values involved in Kracht are approved by DKD (German Metrology Bureau).

　　2、 Function:

1. According to the principle of gear motor, the measurement gear is driven by liquid flow;

2. The gear operates without contact inside the measuring chamber. The bearing components adopt ball bearings with low friction and sliding bearings.

3. The motion information of the gear is sampled by two sensors installed inside the cover plate without contact; A pressure resistant non-magnetic isolation plate is installed between the sensor compartment and the measuring room;

4. When the detection device rotates one tooth product, the sensor emits a signal corresponding to the set tooth product;

5. This signal is converted into a square wave signal by a preamplifier;

6. Dual channel sampling can achieve better resolution and flow direction recognition.

　　3、 Common models:

The regular models include: VCA2FCP1 in stock, VC0.2F1PS in stock, VC0.4F1PS in stock, VC0.2F1PS in stock, equipped with indicators, digital instruments, Kracht oil pumps, and Kracht gear pumps.

　　4、 Precautions for flowmeter installation:

1. To choose a suitable fluid, if the viscosity of the fluid is too high, it is not conducive to its normal operation. Therefore, it is necessary to choose a fluid with a lower viscosity coefficient. Generally, water is used as the fluid in factories, and it is recycled during use, which is more conducive to saving energy. Therefore, the liquid concentration should also avoid being too viscous. When the liquid viscosity is below 5x10-6mm/s, the influence of viscosity can be ignored. Otherwise, measures need to be taken to compensate for the influence of viscosity, such as narrowing the scope of application, increasing the lower limit of flow rate during use, instrument coefficient and Reynolds coefficient.

2. During the testing process, staff should also pay attention to constantly observing the working condition of the flowmeter to see if its data is accurate. Therefore, regular inspection and maintenance are also necessary, especially if there are quality problems with the flowmeter during monitoring, it will have an impact on factories and enterprises. Especially in industrial production, only when the measurement and counting reach a certain standard and meet the conditions of industrial production can the produced products meet the standards. If the measurement data monitoring is inaccurate, it will have an impact on the product. Therefore, timely verification and testing are necessary to avoid serious consequences.
