Perfect monitoring solution for chillers/cooling circuits, HVAC, medical equipment, batching and industrial process control applications.
CHOICE OF THREE PORT SIZES
 Select from 1/2" , 3/4" or 1" NPTF porting to meet system requirements.
EASY MAINTENANCE AND CLEANING 
Has only one moving component, the impeller. Cleaning and maintenance may be performed without removing the sensor from the piping.
HERMETICALLY ENCAPSULATED CIRCUITRY
Withstands the harshest environments.
SEVERAL OUTPUTS AVAILABLE
The standard interface is a 2-wire, 4-20mA current loop. Sensor signal may be transmitted on a low cost wire without degradation. Pulse, 0-5 VDC and relay outputs are also available.
CONNECTS DIRECTLY TO YOUR FLOW MONITORING INSTRUMENTS
Can be connected directly to analog acquisition cards, chart recorders or other monitoring instruments, without external signal conditioning.
SIMPLY PLUMB AND APPLY POWER
 Comes factory calibrated to your flow range specifications.
VALUE PRICING
Combined with low cost operation and maintenance, equals better bottom line savings for your operation.
