WL-8 ultrasonic level meter is instrument of measured material level, which is non-contact, high reliability, cost-effective, easy to install and maintain. It meets the requirements of material level without the contact. WL-8 ultrasonic level meter offers compact size, high performance, and outstanding operation capabilities. Sophisticated design and rugged construction guarantees no maintenance. The meter consists of ultrasonic sensor and electronic transmitter unit. Ultrasonic pulses are emitted by the sensor to the surface of measured medium. Part of reflected ultrasonic pulses are received by the transducer and converted into output electronic signal. The relationship among distance S, sound speed C and transmission time T is: S=C×T/2.
