Welltech high accuracy XEM series flowmeter

Specifications

1.Excitation current automatic compensation
2.Capacitive empty pipe test technology

Welltech high accuracy XEM series  flow meter

 

XEM series EMF is applicable to measurement industrial fluid flow such as metallurgy, paper making, petrochemical, electric power, irrigation works, city water supply and drain etc. There exists unique advantage in flow measurement for big size in water treatment. The conductivity of fluid is no less than 5μS/cm. The production of primary adopts the technology and equipment from Fischer & Porter Germany.

Professional Quality  with  Unique Performance: Conductive rubber earthing and earthing electrode, earthing ring or earthing flange is not necessary. Patent technology, patent No. ZL200420021696.8, ZL200420021698.7 External power driving unit is not necessary for big size Dismountable electrode (optional) Excitation current automatic compensation assures the long-term accuracy Capacitive empty pipe signal detecting, quick response and high accuracy Removable EEPROM
