KUM-C Intelligent Ultrasonic Level Sensor

Introduction

KUM-C Intelligent Ultrasonic Level Sensor (material place，liquid level), is a non-contact, high reliability, cost-effective, easy to install and maintain level measurement instruments. It does not have to contact medium and it can meet most of the requirement of level measurement.

Debugging

Due to the different installation environment of instrument, so before ultrasonic level meter works we must know the basic situation of the required, such as measurement range, zero level, full scale and application field.

Installation

①Measuring range: the meaning of measuring range is very important for meter type selection. Please refer to the diagrams below.

② Emitting angle and false echo
Ultrasonic wave beam is gathered by the probe. The emitting of impulse wave beam is like the light beam of flashlight. The further it is from the probe, the greater the diffusion area is.
Any objects within the range of emitting angle, such as pipe, support, weld joint, reinforcing rib, mixing propeller and hanging object, will lead to strong false echo, specially the objects within the range of emitting angle which are near the probe.
For example, the false echo caused by the pipe at 6m from the probe is 9 times stronger than that caused by the same pipe at 18m from the
probe.

★Try every effort to make the sensor axis perpendicular to the medium surface and avoid any other object within the range of emitting angle, such as pipe and support.
