Is it difficult to calibrate a float level gauge? Teach you a trick

The FGX floating ball continuous liquid level transmitter uses the magnet inside the floating ball to change the resistance inside the connecting rod and the voltage divider circuit composed of a magnetic spring switch according to the liquid level. The smaller the gap between the magnetic spring switch, the higher the accuracy. The divided voltage signal can be converted into 4-20mA or other different standard signals through a converter. The indicator can be used in conjunction with other gauges for remote indication, making it a simple and reliable liquid level indicator.
