Description
Honda HL2000 Ultrasonic Level Meter
Honda HL2000 ultrasonic signal has characteristic that it reflects where the density changes. Submerged sensor transmit ultrasonic signal, then the signal reflects at the interface inside the tank. Some part of signal penetrate into the sludge and it also reflects at the rake or bottom of the tank.
Honda HL2000 Ultrasonic Level Meter is a high-precision, long-range non-contact liquid level measuring system designed for continuous monitoring in deep storage tanks, industrial sumps, chemical reservoirs, and water treatment channels. Manufactured by Honda Electronics Co., Ltd., the Honda HL2000 Ultrasonic Level Meter features a powerful acoustic transducer and digital processor engineered to measure extended fluid distances without physical contact. Equipped with automatic temperature compensation, intelligent echo filtering, a digital LCD interface, and standard 4–20mA output, it provides low-maintenance level telemetry for large-scale industrial and municipal facilities.
Description of Honda HL2000
Ultrasonic signal transfers in the unclear water. There is no need to contact to the measuring object (sludge), the measurement can be done without sinking the sensor deep into the tank.
Technical Overview & Operation
The Honda HL2000 Ultrasonic Level Meter operates on the acoustic time-of-flight (ToF) principle. Positioned above the maximum liquid surface, the high-output transducer emits ultrasonic pulses downward into the vessel space.
When the acoustic pulse strikes the fluid surface, it reflects back to the transducer face. The internal microprocessor calculates the exact transit time ($\Delta t$) of the returning echo and determines the surface distance using acoustic velocity ($v$). Integrated temperature sensors automatically compensate for air temperature variations within the vessel headspace. Advanced echo-processing algorithms filter out false reflections caused by internal tank agitators, structural supports, wall seams, or surface turbulence.
