LZ Variable-area Flow-meter with measuring tube has the characteristics of simple construct work reliable widely used high precision .Convenient installing.Compared
with the Variable-area Flow-meter with glass tube .This series has the characteristics of high-pressure proof high-temperature proof safetyocular reading etc.It can be
suitable to measure the flange usesfloater of normal series uses material of stainless steel .The orificefloat and the tube lining of anti-corrosion series uses the
anti-corrosion material of PTFE(Teflon).
