Summary ?
LZZ Z type metal pipe flow meter is one of the LZZ series. Its measuring tube body with metal, can be used in the medium of high temperature and pressure, measurable transparent medium, can also be measured is not transparent medium, strong and durable, high reliability. Metal pipe flow meter is the role of the converter float displacement through the magnetic coupling from the float height position transformation and shows the flow value. On the basis of mechanical and electrical transformation output electric signal, constitute LZZ Z type data remote transmission type of metal tube float flowmeter. Data remote transmission signal is 4 ~ 20 ma electrical signals.

LZZ-Z type metal pipe flow meter can measure the liquid, gas and steam.
LZZ-Z type metal pipe flow meter is the combination of microprocessor with analog and digital products. The transmitter will be fluid flow signal corresponding to the analog voltage signal into 4 ~ 20 ma two wire system linear output current signal and load the HART protocol communication, using the HART bus intelligent transmitter. As HART bus technology was adopted, with high precision, low drift, strong anti-jamming capability, etc. And can realize remote configuration of instrumentation, monitoring, maintenance, and calibration, and other functions. May constitute a measurement of the production process, the supervision and management system. Mechanical measurement structure is divided into basic (horizontal, vertical type), And with modern popular housing design, beautiful shape and the working chamber isolation, etc. ? ?

JB/T 6844-2015 Metal tube rotameter
JJG 257-2007 float flowmeter ? Operating principle
?
LZZ-Z type metal pipe flow meter by sensors and a converter in two parts, Vertical from bottom to top through the gauge measured medium, will float float gauge, float the built-in magnet steel rollers with indicator testing magnetic coupling. When the buoyancy of the medium, the resistance and float balance gravity float stays at a particular location, float the discretion of the position is the size of the measured medium flow. Float within the magnetic steel and detection of magnetic coupling, make the detection of magnetic rotation. Due to the detection of magnetic steel for radial magnetization, so change of the magnetic field in the hall sensor, the change is proportional to the flow, the magnetic signal into a dc mV hall sensor signal, the singlechip circuit processing, two wire output 4-20 ma dc current signal and linear load in accordance with HART protocol communication digital signal. ?

precautions for use
?

1. ?Metal tube flow meter must be installed on the no vibration of the pipeline, recommend installed in vertical pipe runs, should not have obvious tilt, fluid flow through the instrument from bottom to top.

2. ?For the convenience of maintenance, it is recommended that a bypass piping, so as not to block the maintenance.

3. ?When measuring smudgy medium, magnetic filter should be in upper instrument, make the ferromagnetic impurity adsorption on the magnetic filter, so as to ensure the normal work of the flowmeter.

4. ?set the flow adjusting valve, its location should be set after the straight pipe on the downstream side of the instrument.
? Recommended installation
?
Set the by-pass pipe. Recommend the use of level and lead detection meter installation of vertical degree. Should not be installed on the pipeline of the flowmeter, external force in the proper position of the meter equipped with support, basic is not affected by external force can make the flow meter. ? Data Backup and Recovery Operation
?
Manufacturers for instrument configuration, calibration, data backup to the original information. Illegal if the user& acute;s site adjustment instrument can work normally, the damping input & quot;5678& quot; information transferred to producer, and cover the user illegal error messages, to normal working condition.
