Pressure transmitter daily maintenance 14 points of attention

1. Do not use a voltage higher than 36V on the transmitter, it will easily lead to damage.2. The transmitter should not touch the diaphragm with hard objects, it will damage the diaphragm piece.3. The measured medium can not be frozen, otherwise, the sensor element isolation diaphragm is easily damaged, resulting in damage to the

Application of radar level meter in activated coke desulfurization process

With the increasingly strict environmental protection regulations and people’s awareness of environmental protection, the activated coke desulfurization process, as an efficient and environmentally friendly desulfurization technology, has been widely used in industry. And radar level meter, as a kind of non-contact measuring instrument, is also gradually used in the activated coke desulfurization process because of

Coriolis Mass Flowmeter on an Asphalt Additives System

Accurately measuring the flow of asphalt has consistently presented a formidable technical challenge, primarily due to its inherent characteristics—high viscosity and poor fluidity. Operating within pipelines at temperatures hovering around 200 °C (392℉), liquid asphalt further compounds the complexity. Even at elevated temperatures, the viscosity of asphalt remains persistently high, exacerbated by the presence of
