1Install radarlevel meterWhen injecting, one should avoid the feed inlet, feed curtain, and vortex, as the liquid will produce false echoes with amplitudes much larger than the effective echoes reflected by the measured liquid level. At the same time, irregular liquid levels caused by vortices can scatter microwave signals, leading to attenuation of effective signals, so they should be avoided;

2For containers with stirrers, radarlevel meterDo not install it near the mixer, as irregular vortices will be generated during mixing, which can cause attenuation of radar signals. At the same time, the blades of the agitator can also cause false echoes in microwave signals, especially when the relative dielectric constant of the measured object is small and the liquid level is low, the impact of the agitator is more severe;

3When radarlevel meterWhen used to measure the liquid level of corrosive and easily crystallizable objects, in order to prevent the influence of the medium on the sensor, manufacturers generally adopt a structure with polytetrafluoroethylene measuring windows and separation flanges. The temperature of these components cannot be too high, and the maximum temperature of polytetrafluoroethylene is200℃. In order to avoid the influence of high temperature on the radar antenna and to prevent the presence of crystals on the diaphragm from affecting the normal operation of the instrument, it is required that there be at least one gap between the flange end face and the highest liquid level100—800mmThe safe distance.

Notes:

1Detecting radarlevel meterDon't forget to measure with electricity on, otherwise the measurement is meaningless. When conducting live measurements, the main focus is on radarlevel meterIs the current output normal.

2Using logic pens or display devices to manipulate radarlevel meterWhen conducting signal detection, it is necessary to simultaneously contact different probes with the radarlevel meterMeasure the pins and see if there is a short circuit.

3Checking the radarlevel meterWhen using a filtering capacitor, the positive and negative poles of the electrolytic capacitor should be short circuited first, but they cannot be discharged, which can cause measurement and lead to wire burnout.
