Which instrument should be used to measure the level of solid sodium carbonate powder?
Thread Content
In the alkali dosing system of our company’s flue gas desulfurization unit, there are 2 storage tanks for solid sodium carbonate. These tanks have dimensions of DN3500*15000 mm; they are suspended from the floor via two layers of supports, and their bottoms have a conical shape. The current problem is to measure the level in the storage tank. For this sodium carbonate powder material, which instrument would be most suitable and offer relatively high measurement accuracy? The bulk density of sodium carbonate is taken as 0.7.
An ultrasonic level gauge can be considered; you can ask the manufacturer whether it’s suitable or not.
There must be actual successful implementation cases before one can dare to use it; otherwise, it would just be a useless ornament. Anyway, the radar level gauge can’t be used.
Excuse me, OP, why can’t the radar level gauge be used?
1. If the dust level at the top is not too high, a laser level gauge can be used; it is quite reliable for measuring solid levels. 2. Among non-contact measurement methods, nuclear radiation level gauges can also be utilized
At the same time, it is also possible to use a (guided wave radar level gauge)
The radar can be used; it requires purge air. Radio frequency admittance is the most suitable option for measuring the level of alkali ash; we use it for this purpose. The recommendation of 1111111 is worth considering, as the first two options are relatively expensive, especially the radio frequency admittance.
The manufacturer recommended RF admittance. Our instrumentation specialists said that there have been both successful and unsuccessful cases with this method. I believe it has something to do with the material itself. Have you ever used it on sodium carbonate powder?
During operation, a mixed gas phase layer forms at the upper portion of the material in the silo. This layer interferes with instruments such as radar level gauges and radio frequency admittance level gauges, resulting in inaccurate measurements；
