Safety design method of electromagnetic flowmeter

A safety design method of an electromagnetic flowmeter for applying hazardous area, comprising following steps:

• a) providing an electromagnetic flowmeter, the electromagnetic flowmeter comprising a measuring pipeline and a power supply module, a working fluid being allowed to flow through the measuring pipeline;
• b) defining a first explosion-proof hazardous area in the electromagnetic flowmeter for containing the power supply module;
• c) defining a second explosion-proof hazardous area in the measuring pipeline for containing the electromagnetic flowmeter;
• and
• d) separating the first explosion-proof hazardous area from the second explosion-proof hazardous area.
