Metal tube flowmeter
Product Model:Metal tube flowmeter

[Summary]
The standard LZ series metal pipe float flowmeters are composed of one measuring tube and on side indicator.The site indicator can be installed also with additional electric devices, suitable for liquid and gas measurement.
The flowmeter adopts to variable area measuring principle. The measuring device is composed of one taper measuring tube and floater. The floater can move freely up and down in the taper measuring pipe to change the flow area in the pipe.When the flow changes, the vertical position of the floater inside the measuring pipe changes correspondingly.Through magnetic transmitting system, the position of the floater is transmitted to the dial scale of the indicator to indicate the flow.
In M6、M8、 M9 indicator, the follow-up magnet movement is transmitted directly
to the dial scale.In M7 indicator, when the follow-up magnet rotates, the needle
driven by the cam plate indicates linearly the flow.
[Features]

  1. All metal construction, suitable use for high temperature,high pressure and strong corrosive medium.
  2. Short stroke、compact structure.
  3. Low pressure loss design.
  4. New style magnetic coupling structure ensures that the signal transmission is more stable.
  5. Magnetic filter can be added as customer requirement.
  6. Thermal insulation or tracing heat jacket.
  7. Used in the gas and liquid measurement in all industries. The measurment parts can adopt different  materials to be  suitable  for  different medium.
  8. Intelligent dual-line LCD display,on-site instant/cumulative flow display and back light as options.
  9. Two-wire system,lithium battery,DC24V power supply.
  10. With data recovery、data backup and power fail protection functions.
