The Series HFT In-Line Flow Transmitter provides continuous monitoring of ow
rate levels via a direct reading in-line owmeter with electronics to provide proportional
4-20 mA, 0-5 and 1-5 VDC analog outputs.
FEATURES/BENEFITS
• Provides analog output to monitor application ow and integral direct
reading scale to provide local indication of ow rate
• Increased application versatility with no inlet or outlet straight plumbing requirement
and can be mounted horizontally, vertically, or inverted
• Outdoor or harsh environment installation capable with rugged cast aluminum
construction and NEMA 4X (IP65) enclosure
APPLICATIONS
• Waste water processing
• Lubrication systems
• Process control
• Solar systems
