Lz Metallic Variable Area Flowmeter - China

price: contact company for price

The variable area flowmeters with metal cone is used for

liquids and gases . You can mount it horizontally or

vertically. There are models of local indicating, long-

distance data transmission, corrosive resistant, with

heating device, limit switch, explosion- proof and so on.

Transmission has 0~ 10mA analogue signal output, suitable

for electro- unit combination instrument DDZ- II or DDZ- III.

It has the function of flow accumulating, digital

communication. On- line correcting parameter, various power

supply and so on. We can provide flange and magnetic fliter

on customer' s request. It widely applied to petroleum

industry, chemical plant, power atation, food processing,

pharmaceutical factory and water processing.
