6.2 Operation and performance specifications
6.2.1 Flow rate ranges
Maximum and minimum flow rates through the Sentinel LCT8 ultrasonic liquid flow transmitter are based on the pipe
diameter and the process fluid pressure. The information in Table 18 below is approximate, and it is based on representative
liquid components at a process temperature of 70°F (21°C).
