GENERAL DESCRIPTION:
Benefits:
CHOICE OF THREE PORT SIZES
Select from 1/2” , 3/4” or 1” NPT(F) 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.
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 and 0-5 VDC are also available.
HERMETICALLY ENCAPSULATED CIRCUITRY Withstands the harshest environments.
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 fl ow range specifi cations. VALUE PRICING Combined with low cost operation and maintenance, equals better bottom line savings for your operation.
