Choice
of Three Port Sizes:
Select from 1/2", 3/4" or 1" 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: Stands
up to the harshest environments. |
| • |
Transmit
Several Thousand Feet:
The standard interface is a 2-wire, 4-20mA current loop.
Sensor signal may be transmitted on a low cost wire
without degradation. |
| • |
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. |
