Intelligent pressure transmitters are used to measure the liquid level, density, and pressure of liquids, gases, or vapors, and then convert them into 4-20mA DC signal outputs. The GP intelligent pressure transmitter can also communicate with the Hart manual operator for setting and monitoring.

The LDE series electromagnetic flowmeter is an induction type instrument that measures the volume flow rate of conductive media inside a tube based on Faraday's electromagnetic induction law.

The LUGB series vortex flowmeter is mainly used for measuring the flow rate of industrial pipeline medium fluids, such as gases, liquids, vapors, and other media. Its characteristics are small pressure loss, large range of measurement, high accuracy, and almost unaffected by parameters such as fluid density, pressure, temperature, viscosity, etc.

The LXZ series dual rotor flowmeter (hereinafter referred to as the flowmeter) is currently the ideal generation of volumetric flow meters in China. It is a new type of volumetric flow meter designed and assembled with precision machining.

The LL series waist wheel flowmeter is a volumetric flow measurement instrument, with a measuring section made of stainless steel material and strong anti-corrosion performance.

The LZ series metal tube rotary flowmeter is a variable area flow instrument based on float position measurement. Adopting an all metal structure and Modular concept design, due to its small volume, low pressure loss, large range ratio (10:1), and convenient installation and maintenance, it is widely used in various industries for complex and harsh environments, flow measurement and process control under low flow rate, low flow rate, and various harsh media conditions.

The LGK series orifice plate flowmeter is a high range differential pressure flow device composed of a standard orifice plate and a multi parameter differential pressure transmitter (or differential pressure transmitter, temperature transmitter, and pressure transmitter).

When the liquid level in the tested container rises and falls, the float in the main tube of the magnetic flap level gauge also rises and falls. The long-term magnetic steel inside the float is transmitted to the on-site indicator through magnetic coupling, driving the red and white flipping columns to flip 180 °.

Magnetic flip column level gauge is another type of side mounted, top mounted (bottom mounted) product developed for centralized control. It has the advantages of clear on-site indication and remote control.

UFZ float level gauges are available in both simple and windproof types. By utilizing the principle of buoyancy and force balance, a large float that matches the specific gravity of the measured medium is placed in the container to float on the liquid level of the medium.

The glass plate level gauge can be used to directly indicate the liquid level height in sealed containers, with advantages such as simple structure, intuitive reliability, and durability. However, the medium in the container must be non corrosive to steel, steel paper, and graphite pressure rings.

The UQZ floating ball reed level gauge switch consists of three parts: a magnetic levitation ball, a sensor, and a switch. When the magnetic levitation ball floats up and down along the guide tube as the liquid level changes, the magnetic steel inside the levitation ball attracts the reed tube at the corresponding position in the sensor, causing a change in the total resistance (or voltage) of the sensor.

Small glass tube level gauge, also known as transparent small tube level gauge, has no scale display. Transparent glass tubes can be used to check the liquid level and can be installed with single and double threaded ends.

The UGS color quartz tube level gauge (hereinafter referred to as the color level gauge) is developed using domestic and foreign technology. It utilizes the principle of natural light refraction and reflection in liquids, and with the help of red and green sheets, the liquid phase is displayed in green and the gas phase is displayed in red during measurement.

Ultrasonic level gauge is a digital level instrument that processes signals with a high-performance microprocessor. In measurement, ultrasonic pulses are emitted by sensors (transducers), and sound waves are reflected off the surface of an object and received by the same sensor.
