Illuminating System

A new kind of device measuring liquid level automatically is developed which is composed of camera, illuminating system and industrial computer. It’s based on image measurement technology. The image of the transparent glass liquid level gauge which is installed on the volumetric tank of a flow calibration facility is captured by a camera. After a series of image pre-processing, such as interception, gamma correction, edge detection and so on, the value of liquid level which is the liquid level of the tank can be got by so called peak method. The measurement error is 0.1mm.

Measuring Control

This passage mainly introduces about the design of liquid level and boundary measuring control at sewage re-flooding craft in small split oil field. In order to achieve automatically cutting flooding and re-flooding in the procedure in small split oil-field, the scheme is to test liquid level and boundary by using high performance to price ratio new double level gauge, to utilize electric valve instead of mechanical valve and to choose PLC to control system logic. Eventually, it will reduce the labor intensity.
