NBLB target flow meter is a new generation of flow meter developed by our company. It adopts a new force-torque tube-corner conversion mechanism, transfers the angle through the torque tube, then measures the angle through the high precision Hall sensor and outputs the voltage signal corresponding to the flow change and outputs the standard 4 mA~20 mA square (linear) current analog signal. The instrument has the modern popular enclosure design, the shape is beautiful and each working chamber is isolated, uses the non-contact angle measurement technology to avoid the strain sensor force deformation, safe and reliable.

NBLB target flowmeter adopts a new force – torque tube – rotation angle conversion mechanism. The rotation angle transferred by the torque tube, and then measured through the high-precision Hall sensor, to output the voltage signal corresponding to the flow rate change and standard 4mA~20mA square (linear) current analog signal. The instrument working chambers are isolated. It’s security and reliable by using the non-contact angle measurement technology to avoid the strain sensor’s force deformation.
Operating Principle
After the target 2 is subjected to force, the torque tube 7 is torsional through the target rod 1, and the corrugated tube 5 connected with the drive spindle 3 is driven to rotate. The rotation of the corrugated tube 5 drives the rotation of the magnetic steel components 6.The sensor part detects the change of the rotation angle of the magnetic steel components 6, and the signal processing conversion circuit calculates the corresponding flow value and converts it into the 4~20mA standard signal output according to the inputted angular scalar and the calibrated flow value.Finally, it realizes the flow measurement process
1.The test piece is unmoved, the structure is firm and simple, and the life cycle is long.
2.Fluid medium in general industrial processes (including liquid, gas and vapor), caliber range (above DN10), working state (high temperature and high pressure) can be applicable.
3.It can measure dirty fluids containing impurities (particles): crude oil, sewage, high temperature residue, caustic soda, asphalt, etc.
4.It can meet a variety of installation methods: flange installation straight pipe section type, pair clamp type, plug-in type, split type, on-line plug type.
5.It can be checked by weight hanging method, which brings convenience to user for periodic checks.
6.It has zero and full calibration functions.
7.It has the characteristics of shockproof, strong electromagnetic interference and so on.
