Introduction: The DUT intelligent float level gauge is a modern technological instrument used for measuring and controlling the liquid level, boundary position, and density of various liquids in the production process of various industries. It has the characteristics of high measurement accuracy, stable performance, and strong anti-interference ability. And it can be networked with fieldbus devices that comply with the Hart protocol, achieving digital bidirectional communication and automation of process detection and control. Widely used in industries such as petroleum, chemical, metallurgy, power, and light industry. Working principle: Torsion tube intelligent float level gauge: The float immersed in liquid is subjected to downward gravity, upward buoyancy, and upward torsion tube elasticity. When these three forces are balanced, the buoy comes to rest in a certain position. When the liquid level changes, the buoyancy acting on the float also changes, breaking the balance of force and causing a change in the elasticity of the torque tube, causing it to twist and achieve a new force balance. The torque tube drives the sensor to generate angular displacement, which is processed by a signal processing circuit to generate an electrical signal output that varies with the liquid level. Levered intelligent float level gauge: By using the principle of leverage and the method of measuring stress, the change in buoyancy on the inner cylinder is measured. The high-precision sensor obtains a measurement signal that is consistent with the level change. After processing by the microprocessor, the specific reading is directly displayed on the LCD screen or converted into a standard signal output of 4-20mA through a dedicated circuit. Technical advantages: The DUT intelligent float level gauge has advantages such as high linear processing accuracy of signals, strong anti-interference ability, and stable operation. The operator can remotely operate it in the central control room, such as configuration, monitoring, maintenance, and calibration. This type of instrument has a unique header design, isolated working chambers, and is safe and reliable, greatly improving the accuracy and stability of the instrument. This device has multiple installation methods to meet the installation needs of different working conditions, and can be equipped with explosion-proof and heat tracing functions according to the needs of on-site working conditions.
