Monitoring Carbon Black in Silos

12/12/2006 10:57 AM

Anybody have good luck with monitoring systems in silos? I have 4 silos filled with various grades of Carbon Black that I want to monitor. I recently installed an Ohmart Vega vegaflex sensor but I don't think that it's accurate. I fear that the flow of material doesn't provide a flat top surface for the sensor to reflect off of thereby creating a false signal. The sensor utilizes radar and measures the intensity of reflection for its measurements.

Any suggestions?

Shandong Bestar Carbon Black Factory, the National Owned Enterprise, produces New Technology Carbon Black. All the exhaust gases generated during the production are exploited to generate thermal power, realized the harmonius unity of economic efficiency and environment protection.

The factory is design 200,000 tons annual capacity, to be covered in three phases. The second phase has been successfully put into production, annual carbon black production capacity has reached 120,000 tons. We mainly produce N210, N220, N234, N326, N330, N375, N539, N550, N660, and other various types of rubber carbon black. With excellent product quality, stable production technology parameters, reasonable prices, our carbon black has won praise from customers home and abroad.
