7. Application Scenario
When the use case is for detecting the water level of the toilet tank, please install the device at a desired level of the toilet tank.
Turn on the device after it is fixed to the toilet tank and powered.
The device will detect the status regularly at the MinTime interval.
There are two conditions in which the device will report the status of the detected liquid and the battery voltage at MinTime interval:
a. When the liquid level changes from where the device can detect to where the device cannot detect
b. When the liquid level changes from where the device cannot detect to where the device can detect
If none of the above conditions is met, the device will report at the MaxTime interval.
8. Installation
Wireless Capacitive Proximity Sensor (R718VB) has two magnets on back.
When using it, the back of it can be adsorbed a ferromagnetic material object, or the two ends can be fixed to the wall with screws (should be
purchased)
Note:
Do not install the device in a metal shielded box or other electrical equipment around it to avoid affecting the wireless transmission of the device.
8.1 Measured liquid medium viscosity
8.1.1 Dynamic viscosity:
A.
Less Than 10mPa·s when the normal measurement.
B.
10mPa
<
Dynamic viscosity
<
30mPa·s would affect the detection
C.
Greater than 30mPa·s due to a large amount of liquid attached to the container wall, cannot be measured.
Note:
With the temperature rise viscosity decreases, most of the high viscosity of the liquid by the temperature is more obvious, so when measuring
the viscosity of the liquid when the liquid temperature attention.
8.1.2 Dynamic (absolute) viscosity Explanation:
Dynamic (absolute) viscosity is the tangential force per unit area required to move one horizontal plane with respect to an other plane - at an unit
velocity - when maintaining an unit distance apart in the fluid.
Fixed with screws
