Digital 4 - 20ma Fluid Level Meter Ultrasonic Level Transmitter Low Power Consumption
Digital 4-20ma Ultrasonic Level Meter 5-15m Ultrasonic Level Transmitter
Product Description
KUMA series ultrasonic level meter realizes high digital, communication between machine and human. The CPU applies import industry monolithic integrated circuit, digital temperature compensation and wide voltage input. You can select analog, switch or RS485 serial signal output. Owning the advantage that there is no need to contact the measured medium; it could supply more precise and longer work life.
