1. Do vortex flowmeters need to be powered? Both powered and non powered vortex flowmeters exist, depending on their functional configuration. 1. Intelligent devices that require power must have an external power supply (such as 24V DC) for smart vortex flowmeters with built-in electronic components. The core function of such devices is to convert physical flow signals into standard current signals (such as 4-20mA) or digital signals (such as RS485), thereby achieving real-time interaction with external control systems, data recorders, or industrial IoT platforms. This type of application is currently the mainstream in the market, covering scenarios such as chemical engineering and energy monitoring of combustion sources that require remote monitoring. 2. Mechanical devices that do not require electrical connection use pure mechanical structures. Basic models usually rely only on fluid force to drive internal gears or finger liquid needles, achieving instantaneous flow readings on site. For example, local monitoring points for old pipelines may adopt this solution, but due to the inability to transmit data remotely and limited functionality, the current application scope is relatively narrow, and it is more commonly used as a backup or low-cost scenario option.

When selecting, the first choice is to understand the minimum flow rate, common flow rate, and maximum flow rate of biogas. Most biogas measurement sites do not have a power source, so we can choose a battery powered vortex flowmeter. If users need to bring the display of the meter indoors, an integrated vortex flowmeter can be used. The output signal is led to the flow integrator installed indoors through a cable. The vortex flowmeter can be used to display the instantaneous and cumulative flow of biogas. When installing a vortex flowmeter for measuring biogas, if a valve is installed near the upstream of the installation point, constantly opening and closing the valve will have a great impact on the service life of the sensor, which is very likely to cause permanent damage to the sensor. It is recommended to avoid installing the sensor on a very long overhead pipeline as much as possible. After a long time, due to the sagging of the sensor, it is very easy to cause sealing leakage between the sensor and the flan
