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.
Max particulate size 20 µm Flow range 1 to 50 sccm Operating temperature 32 to 122°F (0 to 50°C) Max pressure 100 psig (6.9 barg) Pressure drop at maximum flow <0.75 psi Accuracy ±2% of full scale Repeatability ±1% of full scale Response time <5 msec Fitting/connection 1/4" compression Analog output 4-20 mA Supply voltage 5.3 to 26 VDC Power consumption 3 mA Wetted materials Aluminum, brass, Buna-N Dimensions 4-1/4"W x 3-1/2"H x 1"D
主要特点:
Great for use when only flow rate is required Install in any orientation without affecting the flow rate An RS-232 option for integrating into more complex systems No moving parts ensure a long, dependable service life
