LZ series of metal tube float flowmeter apply to small flow of the medium low Reynolds number flow measurement, the flow meter on the instructions of a function or the Far East, Far EasTone output to a standard 4 ~ 20mA signal. Limit can be configured

Digital switches, control the police. The instrument has a rational structure, the use of easy maintenance, pressure loss of small, reliable, surveying a wide range and so on.

LZ series of metal tube float a flow meter showed that the spot-and smart-Far EasTone, with indicators show an instant / cumulative flow of liquid crystal display, on the threshold alarm output, and the cumulative pulse output, batch control, the standard second-line system 4-20 mA Current output, and other means for users to provide a very broad choice, and the instruments used Motorola's advanced micro-processing chip and the industrialization of high-quality components to ensure that the flow meter in various places of the excellent performance. Over the years, the metal tube float Flowmeter excellent performance and reliability, and better cost performance, has been widely petrochemicals, steel, electricity, metallurgy, light industry, foodstuffs, pharmaceuticals, water treatment and other industries Favor.

principle:

LZ series of metal tube float flowmeter made by the two main components: measuring indicator and the CPD. Including the measurement of or Cone of the orifice, the director, actuators, float and other components, including magnetic indicator follow-up system, the guide, dial, wait until the line components.

Tested medium flows through bottom-up measurements of the float from top to bottom-up form of a differential pressure, when the float of the Baptist suffered increase in the flow of fluid in the float weight, the float will rise, annulus area increases, the Central gap Fluid flow rapidly declining, from top to bottom Float-pressure lowering, role in the rise of the float with the decrease, until the rise of the Baptist and the fluid balance in the float weight, the float will be stable at a certain location, location float to the level that should be Measured the flow of medium size. Float built-in magnet, the float with the media only move up or down, the movement of the magnetic field with the float changes.

main characteristics:

Apply to small-calibre medium and low-velocity flow measurement
Reliable, maintaining a small amount of long life.
For straight paragraph Yaoqiubugao, wider than the flow of 10:1
Double-largest liquid crystal display, optional scene instantaneous / cumulative flows, which can carry backlight
Uniaxial sensitive instructions
All-metal structure, suitable for high-temperature, high pressure and strong aggressive media

main technical parameters:

Selection:

For example Selection

Air calibration state T = 20 , P = 0.1013Mpa
Filters
If the medium containing solid particles, in the upper reaches of the straight before the installation of the corresponding particle filters to filter out impurities, if the medium of magnetic material containing iron, should be in the purchase of the aircraft at the same time, with my company's magnetic filter to Anti-impact on the accuracy of the instrument and extend the life of instrument. Magnetic filter (see Figure 2), and then liquid material can be 0 Cr19Ni9, 00Cr17 - Ni14Mo2, PTFE and other materials selected.
Installation requirements
1. Instrument can be installed in vertical or horizontal pipes, the vertical flow of the media must be a bottom-up. The level of flow meters and the media should be the arrow on the same direction. Instrument upstream equipment 5 DN long straight, the lower reaches of set 250 mm long straight, the set-conditioning flow valve, its location should be in the lower reaches of the instrument straight after paragraph.
2. Recommend the installation, set up bypass pipeline (see right). Recommend the use of lead-foot hammer and the installation of vertical flow meter testing, to ensure that the flow meter accuracy.
3. Pipes installed in the flow meter should not be subject to external force, in the appropriate place flowmeter installation of import and export support, the basic flow meter can not be forcing.
4. PTFE lined installation (PTEE) flowmeter, fastening flange bolts should be especially cautious, only once excessive demands symmetry fastening tight to prevent deformation of PTFE.
5. In order to avoid shocks measuring fluid within the float, using the instrument to be slow to open the valve, in particular the medium used to measure gas flow, in the lower reaches of the instrument straight after the installation of gas damping device or to the maximum throttle Float to reduce vibration.
