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.
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.
The device has empowered by the surface mounting technology, featuring the design of multiple-layered protection and isolation, with a strong anti-interference capability and high reliability.
It has used the embedded operating system with USB data dump function.
The data storage time could reach up to 720 days.
By using U disk and host computer analysis software, one could call and view the historic curve of process variants and relevant historic data from time to time.
It also could match with various liquid sensors, such as ultrasonic liquid level meter. The device has sound anti-theft and anti-damage and other features.
