? ? Summary ? Vertical reference Is a major structural type LZZ type of metal tube float flowmeter,Medium flows through the pipe from bottom to top. Through the float components, measurement of orifice plate and external magnetic steel on the converter work together to achieve the purpose of measuring flow rate value. ? Operating principle
?
Medium flow float upward lift action, when the float is the upward force, buoyancy and gravity balance, float stays at a particular location, by measuring the position of the float can be measured by measuring the medium flow. Float the built-in magnet steel with converter on the rotating shaft of the magnetic coupling, through the magnetic coupling system, directly into a flow value, the pointer and dial indicator, 4-20 ma current signal or output and load in accordance with HART protocol communication digital signal. ? ? Range of application
?

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 characteristics of the flow meter and use it
# # Suitable for small diameter and low flow velocity. The calibre of the commonly used flow meter between 40 ~ 100 mm. Suitable for low Reynolds number.
# Is lower than other types of flowmeter for minimum Reynolds number.
# The pressure loss is low. Metal pipe flow meter is usually about 4 ~ 20 kpa.
# On the straight pipe upstream requirements is low. After general for the first five times the diameter, 250 mm.
# Have a wide flow range, generally 10:1.
# The application of flow meter is still limited to small and medium caliber, corresponding to the language is suitable for the low velocity of advantages.
# If you use medium and factory calibration medium is different, do flow value correction, calibration, manufacturers need to be done in the test device and the radial scale conversion. General flow meter manufacturer with 20 ℃ and 0.1 MPa water liquid calibration.
# Float flowmeter measurement types: the main measurement object float flowmeter is single-phase liquid or gas, the solid particles in the liquid or gas containing droplets usually doesn& acute;t work, because the float attached to particles in the liquid flow or tiny bubbles will affect the measurements.

? 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.

When using in smudgy medium, float components need to be cleaned regularly, prevent with impurity on the float, float a change in the size, weight, the measurement precision is not guaranteed.
? 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.
