The SLDL2550 Split Type Ultrasonic Water Level Gauge is a high-performance non-contact liquid level measuring instrument. The SLDL2550 Split Type Ultrasonic Water Level Gauge calculates level by measuring the time-of-flight of ultrasonic pulses transmitted and reflected from the liquid surface, delivering stable and accurate readings for water, sewage, and various industrial fluids.
Solidat Applied Technologies Ltd. is one of the leading manufacturers and suppliers of SLDL2550 Split Type Ultrasonic Water Level Gauge in China, and supports full customization for special working conditions. We provide high-quality SLDL2550 Split Type Ultrasonic Water Level Gauge from stock, and welcome customers to request factory quotations. We offer reliable service and competitive pricing for global industrial users.
The SLDL2550 Split Type Ultrasonic Water Level Gauge uses ultrasonic reflection technology to measure liquid level. Installed vertically above the liquid surface, the sensor transmits ultrasonic pulses to the medium and receives the reflected echo. The SLDL2550 Split Type Ultrasonic Water Level Gauge computes the distance between the sensor and liquid surface using the time difference, enabling precise continuous level monitoring.
The SLDL2550 Split Type Ultrasonic Water Level Gauge operates by emitting ultrasonic pulses toward the liquid surface. When the pulse reflects back to the sensor, the instrument measures the total travel time. Combined with built-in temperature compensation, the SLDL2550 Split Type Ultrasonic Water Level Gauge accurately calculates the real-time liquid level, distance, or difference value.
