A compact, dual-function Ultrasonic Gas Flow Sensor that measures gas flow and gas concentration for flow rates from 1 to 25 Liters per minute. This Ultrasonic Gas Flow Sensor uses a unique time-of-flight design with an onboard processor to make highly accurate measurements of both gas flow and concentration. Suitable for use with many gases in an easy to implement format.
Key features of the GB-L1CM1 Gas Flow Sensor include:
Panasonic’s proprietary Gas Flow Sensor offers two gas sensing functionalities (flow and concentration) in one device. This Sensor experiences low pressure loss due to the absence of obstructing objects within it’s flow path.
The Panasonic Gas Flow Sensor provides high measurement accuracy, even with hydrogen gas, because of its’ highly sensitive functionality. Low voltage input allows this Sensor to be Battery operated.
Panasonic Gas Flow Sensors feature an extremely small footprint that permits compact designs.
