Level

Overview

Ultrasonic level meter is a non-contact continuous level measurement product. It offers affordable solution for a variety of applications for water, waste water, petrochemical, chemical, food and beverage. The transmitter is mounted on the top of the tank and transmits an ultrasonic signal down into the tank, the signal travelling at the speed of sound and reflected back the transmitter from the liquid surface. The transmitter measures the time delay between the transmitted and received and calculates the distance.

Features

• Adopt ABS waterproof shell; protection grade IP66;
• Display liquid level, distance, echo waveform and historical curve;
• Automatically detect on-site electrical interference and perform interference suppression;
• Internally integrated temperature sensor to perform temperature compensation for sound velocity in real time;
• Provide alarm current output to prevent the liquid level from entering the range or exceeding the range;
• With built-in 4~20mA current simulation, liquid level simulation, RS485 communication test and other functions;
• With built-in buttons, parameters can be set on site; remote parameter setting can also be performed via RS485;
• All input and output lines have overvoltage and overcurrent protection;
• Non-contact measurement, long life;
