What instrument is used to measure liquid carbon dioxide?
Thread Content
Dear friends: I would like to ask what instrument is used to measure liquid carbon dioxide? Here’s the situation: In our client’s factory, there is a carbon dioxide production facility, and the liquid carbon dioxide produced is stored in low-temperature tanks. When selling carbon dioxide, a low-temperature tank truck arrives, and a pump is used to transfer liquid carbon dioxide into the tank truck. A level gauge is installed on the carbon dioxide tank truck, and staff use this gauge along with the timing of pump operation to determine how much carbon dioxide has been loaded into the truck. Customers' orders are processed in accordance with the sales contract. When loading, it is necessary to load according to the weight specified in the sales contract. Here comes the problem: if the sales contract specifies 10 tons of carbon dioxide, the employees estimate the amount of carbon dioxide loaded based on the liquid level gauge in the tank and the duration for which the pumps are running; sometimes they stop loading after 9.5 tons have been added. The tank truck is taken away to the scale for weighing; if the weight is insufficient, the pipes need to be connected again and the pump started up to fill it, sometimes even a second time. It’s quite troublesome. Now, I’m thinking about installing a flow meter with higher precision on the filling pipeline, so as to directly read the flow rate or weight of the product being loaded. Fill as much carbon dioxide as you want. Condition of carbon dioxide during loading: liquid carbon dioxide, with a pressure of 2 MPa and a low temperature (not measured). Experienced users, could you please advise on what type of instrument should be used to measure liquid carbon dioxide?

The contract should be revised in this regard; such things cannot be absolutely accurately filled – it can only be done to a relative extent. Additionally, there is a fullness gauge on the vehicle, which can also be used. For reference.
I saw it online; you can check out a few more companies.
Install a flow meter. If a mass flow meter is recommended for measurement, vortex flow meters or turbine meters can also be used for loading if final weighing is performed. Ensure that the medium fills the pipeline during loading to minimize vaporization. Our CO2 storage tanks are also at around minus ten degrees; the vortex flow meters used for loading are based on the parameters from the pumps at the factory.

The tank truck carries the substance at room temperature, which is higher than the temperature of liquid carbon dioxide; therefore, significant vaporization occurs during filling. Additionally, the vaporization of carbon dioxide absorbs a lot of heat, and this can sometimes interfere with the filling process due to the formation of dry ice. Pre-cool the medium pipelines and flow meters, and also pre-fill the tank trucks (which is essentially a pre-cooling process as well). The procedure may be somewhat complicated, but it will result in a much better filling quality and help to minimize subsequent problems.
What was said on the fourth floor is correct; this is exactly how we carry out actual project implementation.
If you have the money, use a servo-level gauge; if not, use a guide radar. When choosing a guide radar, make sure that its range of dielectric constant measurements includes your liquid carbon dioxide
Where does the carbon dioxide upstairs come from? What is the customer buying it for?
Emerson’s mass flow meters are better
