What type of meter is good for measuring methanol?
Thread Content
Our plant’s methanol storage tanks are equipped only with magnetic float level gauges; therefore, the amount of methanol purchased has to be determined by weighing. Is it possible to install a flow meter on the pipeline to enable measurement?
Mass flow meters are the preferred choice, followed by positive displacement flow meters
It’s better to use mass for measurement; when it comes to this type of settlement, don’t be stingy with money – the costs saved over time will definitely exceed the cost of a device of better quality
With gravity unloading, the pressure is unstable, making it difficult to implement； There’s no problem with discharging from the pump. Isn’t it usual to weigh the total weight at the factory’s large scale, and then weigh the weight of the empty vehicle after unloading?
Choose a quality flow meter with good performance; it is better to combine flow measurement with weighing.
Our unit uses mass flow meters, but when setting the parameters, pay attention to the low-signal cutoff function. The original mass flow measurement was available, but it’s not clear what the situation is with the current ones; if the settings aren’t adjusted properly, the deviation becomes too large. For reference only!
For trade measurement, a mass flow meter with an accuracy of 0.2% is the best choice, as it is fair to both parties
In the end, weighing is still necessary; the seller needs to know how much cargo has been unloaded from a truck. It seems that flow meters aren’t essential. If a choice must be made, for measuring pure methanol, a metal rotor flow meter will suffice if high accuracy isn’t required. For higher accuracy, a turbine flow meter or a mass flow meter can be used~~
