一、概述
LED-99 series intelligence electromagnetism
flowmeter is a kind of electromagnetic induction
flux instrument, and is a new machine-electrical
product which combine signal detection with
micro-electron intelligent technique. The product
can be divided into showing on the spot type and
remote showing type, It can measure the conduction
liquid of high corrosivity,such as: acid,
alkali,salt and so on. It also can measure the volum
flux of pulp,
mud,Waste water and the suspension of mixture of
solide and liquid. It is widely used in the field of
petroleum, chemical engineering, metallurgy,
foodstuff, papermaking and the environmental
protection,
municipal management,
water supply building,the river dredge etc.
