product overview

UQZ type floating ball liquid level transmitterIt consists of two parts: a liquid level sensor and a current converter. The float changes synchronously with the liquid level, controlling the suction and disconnection of the reed switch, so that the resistance inside the sensor changes linearly. The converter then converts the resistance change into a 4-20mA standard current signal and superimposes it with a digital signal for output. This instrument can display, alarm and control the liquid level of the medium in open, closed containers or underground tanks in the instrument control room. The detected medium can be water, oil, acid, alkali, industrial sewage and other conductive and non-conductive liquids, and can overcome the influence of false liquid level caused by liquid foam. At present, the UQZ floating ball liquid level transmitter produced by our company has been widely used in industries such as refining, chemical, papermaking, food, and sewage treatment, and has been unanimously recognized and praised by customers.

Product Features

• Simple structure: Without any movable or elastic components, it has extremely high reliability and minimal maintenance.
• Easy installation: The built-in structure particularly demonstrates this feature, without the need for any specialized tools.
• Easy adjustment: The zero position and range potentiometers can be used to freely shift the zero position or change the range within the effective range of liquid level detection, and the two adjustments do not affect each other.
• Widely used: Suitable for liquid level measurement in media with high temperature, high pressure, strong corrosion, etc.
