Standard LZ series metal tube trail consists of a measuring tube in and a local monitor. Local indicator can also choose to install additional electrical components for liquid and gas measurement. The trait adopts area-changing measure principle. The measuring part consists of a tapered tube and a float composed of conical. measuring tube can float freely up and down movement, changing the flow area of the pipe, with the flow rate changes, the float in the vertical position of the measuring tube also change accordingly, through the pipe system, the magnetic position of the float passed to the dial indicator to indicate the size of flow values. In M6, M8, M9 indicator, with the rotation of the moving, magnet is transmitted directly to the dial; in M7 indicator, with the rotation of the magnet moving through a linear cam plate, the pointer indicates the value of the size of the flow
Parameters :
Suitable for small-medium-caliber and low velocity flow measurement; reliable, low maintenance, long life; less demanding for straight pipe; wide flow ratio of 10:1; Large dual line LCD display, optional on-site instantaneous / accumulated Flow display, with backlight uniaxial sensitive instructions; non-contact magnetic coupling drive; metal tube all metal construction, suitable for high temperature, high pressure and corrosive media; can be used for flammable and explosive hazardous situations; optional second system, battery, AC power supply; multi-parameter calibration function; metal tube adopts data recovery, data backup and brownout for protection.
