Ideally, we should be able to use a liquid volume sensor to directly measure the volume of the liquid in the container. Well, but in fact, there is no mature liquid volume sensor product on the market.
Because there are various shapes of liquid containers. Such as cylinders, spheres, rectangles, cylinders and squares with hemispherical ends.
So why are we talking about liquid volume sensor here? Don’t worry, we don’t have a mature liquid volume sensor. However, we have A dozen ways for liquid level measurement, with different level sensors. Combined with Sino-Inst’s volume recorder. It can collect, display and convert the liquid level of various regular and irregular tanks in the industrial field into the corresponding tank volume. It is suitable for monitoring, controlling and collecting various process parameters.

Liquid Volume Sensor
So far there is no sensor that can measure the volume of liquid. Because there are various shapes of liquid containers, such as cylinders, spheres, rectangles, cylinders and squares with hemispherical ends.
The height of the liquid in these containers can be detected by a variety of sensors. According to the shape of the container, the volume and weight of the liquid in the container can be calculated.

For rectangles, cylinders or squares, the volume and weight of the liquid can be calculated directly by multiplying the floor area of the container by the height of the liquid. And the corresponding relationship is linear. The hemispherical cylinder and sphere at both ends can be calculated by definite integral. The law of curvature change is the volume formula of the function. Calculate the volume and weight of the liquid according to the height of the liquid.
Monitoring liquid volume solutions
Most of our liquid level sensors can output liquid level signals, such as 4-20mA signal, 0-10V signal, RS485 and so on.
However, the liquid level transmitter alone cannot calculate the liquid volume of tanks of different sizes. It’s too complicated. A separate recorder is required to calculate it.
Therefore, the digital display volume meter can collect, display and convert the liquid level of various regular and irregular tanks in the industrial field into the corresponding tank volume. It is suitable for monitoring, controlling and collecting various process parameters.
So, How to measure volume of liquid?
After the liquid level gauge is installed in your tank, Sino-Inst’s volume display controller/recorder can collect, display and convert the liquid level of various regular and irregular tanks on the industrial site into the volume of the corresponding tank . It is suitable for monitoring, controlling and collecting various process parameters.
The volume meter is equipped with volume download software as standard. Form a liquid level volume comparison table. Import volume meter, suitable for volume conversion of various regular or irregular tanks.
The meter is equipped with RS232 communication interface as standard. Connect with the host computer. Through the volume download software, data writing for regular and irregular tanks can be realized. 1000 sets of data can be downloaded.
LCD Volume Display Regulator/ Recorder is specifically designed for industrial on-site regular and irregular canned liquid, volume and mass conversion.
It is based on a 32-bit ARM micro-processor and equipped with the secondary meter with high-speed AD and high-capacity storage unit.
