Case Study: FMP 40 TDR Level Measurement In Coal Bunker

Levelflex FMP 40 is used to measure the level in coal bunkers to guarantee continuous power production. The TDR instrument outperforms a competitor's ultrasonic instrument that failed frequently in this application.

Coal that is conveyed from the yard is buffered in six bunkers prior to the burner. To ensure a continuous production process, these bunkers have to be filled to a certain level at all times. Since the level measurement is critical to maintain production, each bunker was equipped with two measurement instruments.

Application

• Coal bunker: 45 ft. tall
• 20 ft. x 50 ft.
• 6 chambers
• 2 Measuring points per chamber

After the ultrasonic instruments had been replaced with TDR instruments, the operator experienced a stable and accurate reading even during filling. An additional advantage of the Levelflex FMP 40 is the ToF tool that allows the customer to setup their instruments via HART® in the control room.
