Outline

HNLM-100 Series Ultrasonic Level Meter is an intelligent non-contact liquid (material) level measurement instruments. Product has an automatic power adjustment, gain control, temperature compensation, the use of advanced detection technology and computer technology to improve the instrument's measurement accuracy, there is the interference echo suppression function, to ensure real measurement results. Products can be widely used in various height measurements of liquids and solid materials can also be used to measure distance.

Ultrasonic liquid (material) level meter is divided into a smart body size and sub two types of intelligence but also for two-wire and four-wire two kinds. The following describes the integrated ultrasonic level meter.

First, the main parameters
Four-wire system
Power: DC-24v (18v-30v), (sub-size AC-220v)
Output: 4-20mA (16 bit D / A converter), RS485
Range: 0-20m (any segment) (remote range: 0-40m)
Blind: 0.3-0.6m resolution: 1mm
Accuracy: 0.25% Ambient temperature: -25 ℃ -60 ℃
Protection class: IP65 (remote version IP67)

Two-wire
Power: DC-24v (24v-30v)
Output: 4-20mA
Range: 0-10m (any section)
Blind: 0.3-0.6m
Resolution: 1mm
Accuracy: 0.25%
Ambient temperature: -25 ℃ -60 ℃
Protection: IP65

Second, the installation and wiring

HNLM-100A series integrated ultrasonic level meter for easy installation, the direct use of threaded mounting the sensor:
  ★ distance between the sensor and the highest level should be more than blind (placement height ≥ level maximum height + blind) at the same time to ensure that the sensor should be perpendicular to the axis of the object.
  ★ fixed them necessary, to add a rubber gasket, and away from noise sources as possible.
  ★ due to the presence of wave emitting angle sensor when the sensor placement should maintain a certain distance from the wall.
