1. What exactly is a turbine flowmeter?
The intelligent liquid turbine flowmeter is a new type of intelligent instrument developed using advanced ultra-low power single-chip microcomputer technology, which integrates turbine flow sensors and display integration. It adopts dual row LCD on-site display and has obvious advantages such as compact structure, intuitive and clear readings, high reliability, no external power interference, lightning resistance, and low cost. Turbine flowmeter is the main type of velocity flowmeter. When the measured fluid flows through the turbine flowmeter sensor, the impeller rotates under the action of the fluid, and its speed is proportional to the average flow velocity of the pipeline. At the same time, the blades periodically cut the magnetic field lines generated by the electromagnet, changing the magnetic flux of the coil. According to the principle of electromagnetic induction, a pulsating electric potential signal, namely an electric pulse signal, is induced in the coil. The frequency of this electric pulse signal is proportional to the flow rate of the measured fluid. A flow meter that uses a turbine for measurement. It first converts the flow rate into the rotational speed of the turbine, and then converts the rotational speed into an electrical signal proportional to the flow rate. This type of flowmeter is used to detect instantaneous flow and total cumulative flow, and its output signal is frequency, which is easy to digitize. The induction coil and permanent magnet in the picture are fixed together on the housing. When the ferromagnetic turbine blades pass through the magnet, the magnetic resistance of the magnetic circuit changes, thereby generating an induction sign
2. Parameters to be noted when selecting a turbine flowmeter
Parameters to be noted when selecting a turbine flowmeter: To ensure that it can accurately and reliably measure fluid flow, the following key parameters need to be noted: Measurement medium state: Core point: Firstly, it is necessary to clarify whether the measurement medium is gas or liquid.
. Turbine flow meters are mainly used to measure liquid flow and are not suitable for gas measurement. Attention: Ensure that the selected flowmeter type matches the physical state of the measuring medium to avoid inaccurate measurements or equipment damage caused by selection errors. Measurement caliber and flow range: Core point: Determine the size of the measurement caliber and the required flow range. Attention: Verify the suitability of the selected measurement aperture through the flow range. Ensure that the measuring diameter of the selected flowmeter can cover the actual flow range
