UZ Float level gaugeDetailed product description：

Overview
The UZ float type liquid level gauge is a simple liquid level measuring instrument, which is suitable for measuring the liquid level of tanks, tanks, oil fields, oil depots, and other tanks storing corrosive media in petrochemical systems, as well as for low-priced liquid level measurement of water towers (water tanks) in general enterprises and civil buildings, to solve the difficulty of manual liquid level measurement.

Main technical indicators
1. Measurement range: Choose freely within 0-20m
2. Indication accuracy: ± 20mm
3. Working pressure: normal pressure or ± 200mmH2O (with V-shaped sealing tube)
4. Medium temperature: -30 to+300 ℃
5. Medium density used: ≥ 0.4g/cm3
6. Verticality of guide wire installation: ≤± 5mm

working principle
The UZ float type liquid level gauge is designed based on the principle of force balance. When the liquid level is at a certain height, the weight of the float is W, the weight of the heavy hammer needle is W1, the buoyancy force F experienced by the float immersed in the liquid, and the system friction force is f. In equilibrium state: W-F-W1-f=0
When the liquid level rises, the buoyancy force F increases, W、W1、 Both f and f remain unchanged, the balance of the above equation is disrupted, and the pointer of the heavy hammer slides down. A new equilibrium is not established until the F force decreases to its original value. If the F force keeps increasing, that is, the liquid level keeps rising and the pointer keeps sliding down. On the contrary, if the liquid level drops, the hammer pointer rises to indicate the height of the liquid level.
