The APT9500 Series is a transmitter of differential pressure flowmeter. Differential pressure can be converted into flow value via microcomputer technology and flowrate, totalizer. The differential pressure can be displayed directly in LCD screen. It's equipped with strong output function: 4-20 mA, pulse and HART. APT9500 is widely used in differential pressure sensors flowmeter such as orifice, venturi,annubar, v-cone etc. It has high stability and high accuracy.
