Loop Powered Ultrasonic Sensors Internally Calculate Flow Rates and Volume
Automation Products Group, Inc. introduced the LPU-2428 Loop Powered Ultrasonic Level Sensors with microprocessor control to internally perform volume, flow, and totalization calculations. These IP65 rated sensors provide a 1 foot to 25 foot (0.3 m to 7.62 m) detection range. They are designed for liquid flow-rate and volume measurement applications. The sensors provide an output directly proportional to the flow rate, and users can select flow rate units of per second, per minute, per hour, or per day. Standard volume units include cubic feet, millions of cubic feet, gallons, cubic meters, or liters. For volume measurement, the sensors have built-in formulas for most industry-standard tank shapes. They feature a rugged PVDF (Kynar) transducer housing and PC/PET chemical resistant sensor housing, and are easy to install using industry standard 2-inch NPT fittings. These sensors can operate in temperatures from -40°F to 140°F (-40°C to 60°C) and deliver 0.1 in. (2.5 mm) resolution with accuracy of ± 0.25% of the detected range, and response time of 0.6 to 3 seconds depending on the output range.
