Jiangsu micro metal tube rotor flowmetersummary:

LZ seriesAdopting an all metal structure and modular concept design, it is widely used in various industries for flow measurement and process control under complex and harsh environments, low flow rates, and various harsh medium conditions due to its small size, low pressure loss, large range ratio (10:1), and easy installation and maintenance.
The LZ series metal tube float flowmeter has multiple measurement forms for users to choose from according to different user needs and occasions; According to the output form, there are local indication type, remote transmission output type, and control alarm type. According to the output form, there are local indication type, remote transmission output type, and control alarm type; According to explosion-proof requirements, it can be classified into three types: ordinary type, intrinsic safety type, and isolated explosion-proof type.
The LZ series metal tube float flowmeter adopts the internationally advanced Honeywell non-contact magnetic sensor for detecting changes in magnetic field angle, and is equipped with a Motorola microprocessor system. It can achieve functions such as LCD indication, accumulation, remote transmission output (4-20Ma), pulse output, upper and lower limit alarm output, etc. This intelligent signal transmitter has high accuracy and reliability, and can completely replace imported instruments of the same type. It also has the characteristics of high cost-effectiveness, multi parameter calibration, power failure protection, etc.

Jiangsu micro metal tube rotor flowmeterStructural principle:

The LZ series metal tube float flowmeter consists of two parts:
Sensors - measuring tubes and floats;
Signal transmitter - indicator;
There are four types of liquid contact materials for sensors: stainless steel, Hastelloy, titanium, and stainless steel lined with PTFE; Users can meet the pressure resistance and medium anti-corrosion needs of the process according to different corner liquid materials. According to different measurement requirements, users can choose different indicator combinations when selecting to achieve different measurement requirements. The measurement of flow is completed by the transmitter inside the indicator, which couples the magnetic steel to sense the change in float position to indicate the flow and transmit the signal remotely. When the measured medium flows through the measuring tube from bottom to top, the float is balanced by the vertical upward pushing force of gravity, buoyancy, and fluid velocity. The float is relatively stationary at a certain position, which varies with the ring area of the float and the cone tube, as well as the fluid velocity. The position of the float corresponds to the flow rate of the measured medium.
