Calibrating a capacitive level gauge is quick and easy, and can be done in six steps. Before calibrating your capacitor, take inventory of the buttons and hardware, to first familiarize yourself with the buttons and display you’ll be monitoring.

Step 1: Press “Up” Buttons

To begin calibrating your capacitive level gauge, the first step is to connect the loop power supply and ammeter to “plus” and “minus”, and then connecting the other end to the calibrator. Press both “up” buttons, holding down for 3 seconds, then let go.

Step 2: Press ”Down” Buttons

Next, the level gauge will have to be placed in calibration mode. To do this, press both “down” buttons, holding for 3 seconds again, and let go. At this stage, there should be no water on the level gauge.

Step 3: Press “Z” Until You Reach 4mA

Now, the level gauge should be calibrated at its zero point. This is the low scale, and shows as 4mA. To reach this level, press down on the “Z” button until the display reaches 4 mA.

Step 4: Raise Water Level

Once the device gets to 4mA, fill the column with water, so that it can reach the high level of the level gauge. This is known as the “reference water”.

Step 5: Adjust Span to Indicate 20mA

After the water reaches the top of the column, it is time to get the appropriate, full scale reading of the level gauge, at 20mA. To do so, press the “S” buttons until the device reaches 20mA.

Step 6: Verify Low Water Level Is 4mA

Finally, return the water level to zero, to verify that the low water level is reading at 4mA.

1. Good versatility. Level gauge can measure all kinds of tanks, spherical tanks, vertical tanks, horizontal tanks, and other irregular tanks

2. Two-wire system. 24V DC power supply, lower power consumption, safer. Reduce wiring costs.

3. The sensor realizes non-contact or non-invasive measurements to improve the probe’s resistance to harsh process conditions.

4. Stm32 microcontroller technology embedded in the application makes precision a more accurate, more intelligent instrument.

5. Easy to install. Large installation space and other auxiliary facilities are not required. The level gauge is easy to install, maintain, and use.

6. It can not only display on site but also send a control signal to connect DCS or SIS system.

7. Strong adaptability, a wide range of applications. It is not affected by dielectric conductivity, dielectric constant, pressure, and so on, and has strong adaptability to the physical and chemical properties of the measured liquid.

8. Non-contact measurement. The ultrasonic transducer is installed at the bottom of the tank wall. The level gauge is not affected by the medium. No hole is needed.

9. There are no mechanically movable parts. Avoid mechanical failure, no wear, and tear, long service life, lightweight, maintenance-free.

10. Continuous measurement.

There are many advantages of water level controls, also known also level gauge, including:

1. POWER SAVER

Living in an age where we need to be more conscious of the energy that we use, a water level controller is ideal at saving power. Normally, regulating water levels can consume electricity and wastewater. However, with automatic controllers, the electricity usage is limited as well as less water needed to regulate supply.

2. MONEY SAVER

A water level controller helps save money by limiting the waste of water and electricity. These devices accurately regulate how much energy is used to protect against any unnecessary water/electricity usage. Over time, the money saved is quite substantial.

3. AUTOMATIC

Another notable advantage with these devices is that they regulate on their own. Eliminating manual operations with a timer switch, the frustrations of manual monitoring water tanks are minimized. Water levels are maintained at the appropriate levels thanks to the automatic operations of these devices.

4. WATER MAXIMIZATION

On average, water pumps are used more during midday. A water level controller can maximize the water usage provided during midday while automatically lessening the water usage at night. This results in an appropriate level gauge of water at all times being maintained, while providing you with the maximum use of your water at the appropriate times.

5. RELIABLE ELECTRONIC DESIGN

Addressing the durability problems found in earlier designs, the solid-state electronics in the newer models help to eliminate them. Not only do they help to eliminate the durability issues, but they also create considerable savings of the life span of the unit with an advanced modular design. In order to minimize problem areas of these designs, the only moving parts are the relays. These relays are easily replaced and tested by any skilled operator or electrician while being an inexpensive part.

6. NEW CONTROL MINIMIZE FOULING & DETERIORATION

Proving to be less costly, over time, than the original float design for the ‘toilet tank’. The solid-state electronics are designed to minimize volt usage (less than 1 volt). This directly minimizes the mineral fouling, plating, rusting, and deterioration of probes, proving to be safer and more efficient. These factors extend the life span of the controllers significantly, which saves money and energy.

7. EASY INSTALLATION WITH LED MONITORING

These new solid-state electronics and integrated electronics offer superior performance, hassle-free installation, and lower cost to operate over time when compared to the lifespan of the original design. For continuous monitoring, the integrated firmware and digital dry-contact circuitry easily and quickly connect to the automation systems of a building. Each function of the integrated electronics and relays use LED lights to offer operators the ability to visually scan them in order to verify proper operations.
