Alarm values for temperature and level of coal tar storage tanks
Thread Content
The coal tar in this project is at normal temperature and pressure, but steam heating is required during storage; the storage temperature should generally be between 40–60°C. Thermometers and level gauges are installed on the storage tanks, but I would like to know what the upper and lower limits for the temperature alarm values are What are generally the upper and lower limits for the alarm values of the liquid level gauge in storage tanks? How is this generally viewed? Is there any way to calculate it? Are there any other rules?

You should ask the engineering team about these aspects: the design requirements for the storage tank, such as temperature and liquid level alarm values, as well as the flow rates for liquid in and out. Generally, high-level alarms are used to prevent overflow, while low-level alarms are intended to avoid disruptions in production due to a lack of liquid.
