【Abstract】 A laser range finder DISTO and a V/I converter AD421 are applied, and a nocontacting laser liquid level monitoring system is proposed according to the national intrinsic safety. This system has such properties as low cost, easily being practiced, high accuracy and being fit in combustible and explosive environment. At the same time, it is the new noncontacting intelligent instrument and can replace the widely applied secondary device in the area of measurement of the liquid level, having an excellent application prospect.更多还原
