Six, transformation indicator:
Converter is actually change the height of the cone tube float into the corresponding scale of volume flow.On the output signal of points: there is local display and remote transmission signal output:
1, on-site display type: by in situ indicator of follow-up magnetic steel and the float inside the magnetic coupling, and turning, at the same time, through dial, electric pointer indicates that traffic at this time 
Type 2, intelligent remote transmission, by intelligent indicator of follow-up magnetic steel and the float inside the magnetic coupling, and the rotation, sensing magnetic steel and pointer at the same time, through A magnetic sensor to magnetic field changes into electrical signal, after the A/D conversion, digital filtering, microprocessor processing, D/A output, LCD liquid crystal display (LCD), to show the size of the instantaneous flow and cumulative flow.

Seven, structure, classification:
1, high temperature structure type (G)
High temperature structural type (G) is used for medium temperature is too high or too low and need to measure the rate of flow of pipe heat preservation and heat insulation measures of medium measure.High temperature structure is increased the measuring tube and the distance between the indicator to increase heat dissipation, increasing the thickness of insulation material, ensure the indicator work in allow ambient temperature range.Type selection for the "G".
G type metal pipe flow meter can measure the temperature - 80 ℃ to + 300 ℃ medium flow.
2, the structure of the device with damper (Z)
Damper is structured for flow meter inlet flow (pressure) unstable when the medium flow measurement, especially for the measurement of the gas.
3, the structure of the clamp cover model (T)
Clip model structure used for heating or cooling, such as the high viscosity and crystallization medium flow measurement.In the jacketed by heating or cooling medium, make the low boiling point and low solidifying point fluid evaporation and crystallization.
Import and export of heating medium connection, the standard to use HG20594-97 DN15 PN1.6 flange, other connection flange specification can be indicated with factories, jacketed level of pressure is 1.6 MPa.
Clip model see FA standard flowmeter flowmeter structure flange, shape size.
4, high pressure type structure (Y)
High pressure type structure used for pressure is greater than the standard level of measured medium flow measurement.High pressure type structure as shown in the figure below.The recent series of FFM64 zui high pressure can reach 32 mpa.Additional high pressure type flowmeter can provide built-in magnetic filter, the installation height is 350 mm.FA, FB and FC zui pressure to 10 mpa.
Eight, troubleshooting methods: 
1, check alarm value set size in the SU. 
2 d values cannot too big, check the deviation. 
The logical function, FUN, whether it is right.HA - A said cap is logical.LA -a said the lower limit is logic 
4, circuit board fault, replace the circuit board. 
5, if the LCD bar code instructions correct output without action, can check whether the external power supply and external power of the cathode is connected to the instrument power supply of the cathode. 
If metal pipe flow meter in use dithering, could be determined according to the extent of jitter is what range of jitter.Jitter is divided into slightly shaking, moderate jitter and violent shaking. 
1, the slight shaking: generally caused by fluctuations in medium.Can be used to increase the damping ways to overcome. 
2, moderate jitter: generally caused by medium flow state.Is often caused by unstable operating pressure of medium for gas.Can use voltage or current regulator devices to overcome or increase the instrument air damping. 
3, intense shaking, mainly due to the medium pulse, pressure instability or users are given gas pressure, temperature and flow of the operating state of inconsistent with the actual state of instrument, have bigger difference meter range. 
Metal pipe flow meter as long as the use method is correct, pay more attention to maintain at ordinary times, can ensure the normal use of it.

Nine, product maintenance:
1, in the long-term use process, the pipe will inevitably have a ferromagnetic impurity adsorption on the float, it would float jammed or affect measurement accuracy, need to clean them often float inside the sensor;If the installation of magnetic filter, also want to make regular cleaning.
2, instrument indicator is equipped with electronic components, instrumentation connection or remove the shell and the screw to tighten, must ensure that shell sealing, to prevent impurities, or other material into the water, but also ensure the reliable earthing of the instrument housing.
3, meters installed, in * times when using, should pay attention to:
Open valve to avoid pressure impact spacing device to float against, causes the damage of instrument, must open the valve slowly!
Measuring gas meter is equipped air damper, zui to large extent reduce the oscillation of the float;In order to ensure the stability of float, and can be installed in the export of instrument a throttle valve.
4, for remote transmission type instrument, first of all to ensure the instrument connection right after, can live;For the dangerous situation, must choose explosion-proof type, use and install according to the requirements of explosion-proof.

Ten, installation considerations. 
1, checked out after remove the filler of the flow meter, flow meter should be installed vertically on the no vibration of the pipeline, such as horizontal installation, should additional specifications when ordering.The center line of the flowmeter and the vertical Angle should not exceed 5 °. 
2, new pipelines in tube flow meter before installing a new pipeline should be rinsed clean, if the medium to be measured particle impurities or bubbles, filters should be installed in the upstream flow meters or set the outlet, fluid when installation must flow from the bottom up, if the fluid flow from the top down, the meter doesn't work.If measured medium is pulsating flow, should be in the downstream set appropriate size buffer device, such as buffer tank to eliminate pulsation. 
3, to facilitate the check meter zero and disassembling maintenance and debugging, the cut-off valve should be installed at upstream or downstream flow meter and the by-pass valve. 
4, a meter installed by the regulation, should be closed either upstream or downstream flow meter cut-off valve, check instrument and secondary instrument connection again, and, after open secondary instrument power the instantaneous flow shall display to zero.
