???Summary?LZZ-S type metal pipe flow meter can measure the liquid, gas and steam, has strong, safe, durable, easy maintenance, instrument strictly straight pipe upstream requirements, etc. For small flow and low Reynolds number flow measurement, compared with other flowmeter has the unique superiority. Especially suitable for measuring the corrosive strong, turbidity and dirty liquids. This product is widely used in chemical, petroleum, pharmaceutical, food and beverage industries.The product 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.??Production enforce standard

?

LZZ-S 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
?

In view of the working principle of the instrument meter must be installed in vertical pipe runs, and the flow of the medium, must be from the vertical. Fluid set five times the native caliber long straight pipe upstream and downstream straight pipe set 250 mm long, 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.
