差压流量计

仪器简介：

This relatively low-cost volumetric flowmeter is great when only a 
basic flowmeter is required. The flow rate is determined by measuring
 the pressure differential across a stack of stainless steel laminar
 flow plates, a technology that is more tolerant of pressure 
variations in the flow stream. This design has no moving parts 
making it more dependable. Models are available with an analog 
output (0 to 5 VDC or 4 to 20 mA) or voltage output (0 to 5 VDC) 
and with RS-232 communication capability.
