The review and outlook of mill level measurement;

Based on the analysis of the operation conditions of Lurgi gasifiers and due to the disadvantages of γ level detector attached to the ash lock and the difficulties in the popularization of such detectors, the authors put forward a new method to determine the lever of ash lock by detecting the temperature of ash lock with a thermocouple.

Based on sum up of installation situation of operation high level and alarm high level and its application result.

The research is directed at the requirement of new machine electricity centralized equipment for present grain processing enterprises and the determination control machine of the position about bulk material is Studied and produced,at the same time,it possesses the determination control of material position,flowing material control and automatic warning of multiplex technological points.

This paper proposed a design of material position detection based on ATmega8 MCU.

Electrostatic potential distribution in gas-solid fluidized beds and measurement of bed level;

A new method based on the acoustic emission(AE) signals for measuring the bed level was proposed to solve the insecure and imprecise problems of the nuclear level gauge.
