Tank monitors or sensors for your RV enable regulation of the water flow. For any RV, the prime concern is to maintain the water level; therefore, you can add these sensors to the storage tanks.
How to Read RV Tank Monitors? You can read RV tank monitors to check the water level. There are two types of monitors or sensors, like capacitive and probe sensors. It also features lights that illuminate when you check the water holding tank levels (F, 1/2, 2/3, 1/4, and E). When the freshwater level in the tank is low, click the button to see the water level and then turn on the valve to refill it. After it fills up, press the corresponding tank button to see its status. You should not fill the grey and black tank to F-level.
When you need to camp outside in the countryside or at a hill station, where no utilities are present such as water, you keep water in motorhome tanks for your use.
For this purpose, these RVs have three tanks for water. Among these tanks, one is used to store fresh water, the other is for routine usage such as washing purposes, and the third is for holding sewer or wastewater generated during your whole journey.
To avoid this, you need to keep an active check on its wiring, contaminations on the sensor’s probe, and panel screen of your RV.
Types of RV tank monitors
These water-holding tanks have sensors that send electrical signals to the monitoring panel that converts them into a visual representation.
Before understanding RV tank monitors readings, you need to understand the types and functionality of these monitors.
It will help you purchase a better one and then use it efficiently. The most common tank sensors used by RVers are probe and capacitive. Both are low-wattage open circuit sensors.
In probe type sensor, a probe connects to the tank, which is in contact with the liquid level. This probe attaches through the wire with the monitor panel.
So, you can see the readings, like Empty(E), full(F), ½, ¾, 1/4, or Empty(E), 2/3, 1/3, or Full(F) after liquid level in the tank accomplish the circuit with this probe sensor, light on the monitoring panel will illuminate.
This type of sensor is considered the most expensive and most accurate. Therefore, most RV users select capacitive sensors as tank monitors.
This type of sensor will tell you the reading of water level in percentage that shows the accuracy approximately 9%.
How monitor panel detects the water tank level?
RV tanks have the sensors or the probes that fit in these, and this probe operates like an open circuit.
As the water inside the tank increases or decreases at the same pace circuit of this probe opens or closes. This circuit then produces an electrical signal through a wire to an electrical panel installed in your RV.
The signal transforms into a digital signal, and characters in the form of water level appear on your monitoring panel.
Each tank side has these sensors at full(F), ½, ¼, ¾, and Empty (E). The probes connect to their correspondence location on the monitoring system panel.
How to read and calibrate RV tank monitors?
These monitors are usually present inside or on the exterior of the water tank in a sequential level like Empty(E), ¼, ½, ¾, and F (Full).
The Lights on the monitoring panel will activate when the water level reaches specified levels.
These indicators help to detect underfilled or overfilled fluid capacity. When it detects that your water holding reservoir is full, protect the filling of more water that leads to overflow to cause a disturbance.
The Monitor system displays the different water levels in the RV, such as grey, fresh, and black.
The monitoring panel also has a battery button option which shows low, good, fair, and full range. When you click this button, a light will illuminate, indicating the capacity; if it requires charging, plug in the switch.
This panel has the corresponding water type button and the reading of water levels like Full(F), ½, 2/3, and Empty(E).
When you feel the water level is down, press the particular button that shows the range with the light illumination. When the water tank fills up, the light will turn on to show the full(F) indication.
I will guide how to accurately find or check water levels in tanks after error or misreading. The tool you need for its determination is the small screwdriver.
When your grey tank shows it fill up, check it is filled or not by pressing the corresponding button.
You can see each button on this panel has a small hole in front of each tank button. But these small adjustment holes do not present in each motorhome monitoring system.
You can read freshwater tank levels easily. You have to turn on the valve to fill the tank. When the water level is complete, turn this valve off.
After its filling, press the freshwater(F) button with putting screwdriver inside that hole. When you turn it to the left, the light will turn off from (F)full to backward. When you turn it to the right, all indications on this panel will illuminate.
Reading of black and grey holding tanks is entirely different from the freshwater.
When the panel shows the grey or black water level is complete, we do not need to fill each tank.
When you press the grey button, it shows the current water level. Next, open your kitchen faucet, add water when it reaches full (F), the light will start to blink, and close the sink faucet.
Why do you need to read tank monitors in your RV?
These are necessary during dry camping or the absence of sewer connections or water depletion. These sensors or monitors will indicate whether the water level is empty or full.
Inaccurate or improper reading can cause by various reasons. Sometimes, these RV monitors do not read the liquid level accurately inside the motorhome.
It may happen due to malfunctioning of these tank monitors in your RV. It is like a circuit; if anything hits or covers these sensors, it can mislead the circuit to assume the water level is complete or empty.
Black and grey water tank readings can be incorrect when debris or tissue paper is stuck with the internal sensors.
Possible problems encountered by tank monitors are contamination of probe reading tank level, problem inside PLC screen converting an electrical signal into digital numbers for reading, and worn out the wiring of sensors attached with its sensor and screen.
You have to clean the sensor to avoid any misleading information. By adopting cleaning techniques, problems can resolve.
