HD320 series | Ultrasonic Level Meter|HD320 / HD323

Features
●Two-wire interface can suppress the cost of installation, wiring and operation.
What is two-wire system?
Two-wire system supplies electric power through the data line. Electrical wiring is completed only with two lines, power + data and ground.
|
●Four screen mode can be selected

●Large display is adopted for HD323 (Display size : 50 x 25mm, 49% larger than HD320)
●Mask function
Unnecessary signal can be eliminated from the received signal by manually.
Echo signal from existing structure positioned between sensor and target cause interference. Mask function removes these unnecessary echo effectively.
Usage
Measurement of liquid level in a tank
Measurement of sewage level inside pipes
Measurement of water level in lakes, ponds and rivers

HD1200 | Ultrasonic Level meter

· Advanced level sensing algorithm suppresses the noise level and artifacts and enabled stable measurement.
· One main unit handles two sensors at once. Two different types of sensors can be installed and each may measures different range.
· Data logging function to micro SD TM.
· Flow measurement by measuring catchment level is possible.
Usage
· Level control of liquid, powder or grains in a tank
· Level measurement of pond, lake or river
· Open channel flow measurement (catchment level)
