The KUS550 is a compact, low-power ultrasonic level meter featuring high sensitivity and wide application scenarios. Its IP68 protection rating and PVDF shell make it suitable for demanding industrial environments.
- Compact size for easy installation
- Wide working frequency bandwidth
- High sensitivity for accurate measurements
- Versatile for multiple application scenarios
The KUS550 low-power ultrasonic level gauge is designed for efficiency with low operating current, short settling time, and excellent stability. It features:
- Digital temperature compensation
- Wide operating temperature range (-40 to 85℃)
- High precision with 0.1mm resolution
- Shock resistance and high reliability
- Easy installation and use
Industry Applications: IoT, water supply systems, industrial control, municipal engineering, wastewater treatment, hydropower, mining, petrochemical, food processing, and more. Enables real-time monitoring and cloud data integration for efficient system management.
The KUS550 achieves ultra-low power consumption through:
- Specialized low-power ICs
- Precise circuit power control (transmitting, receiving, and MCU circuits)
- MCU sleep mode when inactive
In low power mode (Mode 2), sleep current is less than 0.3mA (0.00099W at 3.3V).
For temperatures below 0℃, proper protective measures must be implemented. When mounting in a through hole using steel nuts, ensure fixation at the middle of the housing thread.
