Flowline Ultrasonic Level Gauge LU80/LU81/LU83/LU84

【 FLOW LINE Ultrasonic Level Gauge LU80/LU81 】 Basic Description

Flowline Ultrasonic Level Gauge LU80/LU81/LU83/LU84
EchoSpan ® Ultrasonic level gauge
The universal ultrasonic liquid level transmitter adopts a 1-channel 4-20mA signal output, which can perform continuous liquid level measurement with a maximum range of 32.8 '(10 meters), and can be configured through an integrated button display module. This type of non-contact liquid level sensor is an ideal choice for corrosive, ultra pure, viscous, or contaminated liquids, and is widely used for liquid level measurement in large storage tanks, daily tanks, lift pump stations, and process tanks.

Flowline Ultrasonic Level Gauge Product Features:

From 9.8 '(3 meters) to 32.8' (10 meters), there are 4 range options available

The integrated button display module allows for quick configuration

The LCD display screen displays the liquid level height in inches, centimeters, or percentages

2 "or 3" narrow beams are suitable for applications with limited measurement space.

Intelligent failure protection and diagnostic feedback facilitate troubleshooting

Sensor made of polyvinylidene fluoride (PVDF) material and NEMA 4X housing made of polycarbonate (PC) material, suitable for corrosive liquids

Automatic temperature compensation ensures accurate measurement
