How to correctly choose German BURKERT flowmeter

At Bürkert, processes are tightly controlled and together they form a learning organization. Because of its close contact with customers, the organization optimizes itself every day. As a medium-sized manufacturing and service company, it is natural for us to adhere to this concept of proximity to our customers. By continuously expanding our network and promoting workflow optimization in various departments, we can better exchange experience related to fluid control. We insist on customer-centeredness. Whether it involves individual components or individual system solutions, this is our fundamental principle.

It is not easy to correctly select a suitable flow meter. Not only must you be familiar with the technology of flow meters and production process fluid characteristics, but you must also consider economic factors. In summary, there are five aspects, namely performance requirements. Fluid properties, installation requirements, environmental conditions and costs. BURKERT mass flow meter (MFM) type 8006 is suitable for measuring mass flow of high air flows. Thermal in-line sensors are located directly in the airflow and therefore respond very quickly. The Model 8006 has the option of calibrating on two different gases, which the user can switch between. As electrical interface, analog standard signals and fieldbuses can be used. MFM type 8006 is specially designed for use in harsh environments due to its low sensitivity to contamination and high degree of protection.

Burkert flowmeter is an instrument that measures gas flow. Its measurement value is not inaccurate due to fluctuations in temperature or pressure, and does not require temperature and pressure compensation. The mass flow controller not only has the function of a mass flow meter, but more importantly, it can automatically control the gas flow, that is, the user can set the flow rate as needed, and the MFC automatically keeps the flow rate constant at the set value, even if the system pressure Fluctuations or changes in ambient temperature will not cause it to deviate from the set value. Simply put, a mass flow controller is a gas flow stabilizing device that can be manually set or connected to a computer for automatic control.

For Burkert flow meters, you need to buy ones with signal output, pulse or current output type. Connect this signal to a PLC or flow totalizer, etc. The PLC receives the signal and calculates and accumulates it. After accumulating to your set value, it outputs a switching signal and controls the solenoid valve to close. PLC is usually used in conjunction with a touch screen. Operate on the touch screen and enter the amount you want to add. PLC control is better than calculator, and it can control several kilograms very accurately. The calculator has a large error and is inconvenient to operate, so it is suitable for working conditions where a lot of addition is required.

The flow rate displayed by the flow meter is generally accurate. Because the flow meter must be tested before leaving the factory. 4-20mA is the current signal simulated by the electromagnetic flowmeter from the flow measured by itself. Therefore, when the flow displays of the two are different, it is caused by the inconsistent settings of the two, and has nothing to do with the flow accuracy displayed by the flow meter itself. As long as the range of either of the two changes, the PID output signal will change accordingly. The flow meter always displays an accurate value, and the flow meter range changesThis means that the 4-20 mA output also changes, and the PID will change. The electromagnetic flowmeter is an analog electronic circuit. The flowmeter detects the flow rate by detecting the current passing through the flowing water through the electrode. If you want to modify the instantaneous flow rate, you can only modify the instantaneous feedback current value. You only need to add a current stabilizing device or a spoiler device to the feedback circuit.
