| FLOWSTAT Low Cost Turbine Flow Meter |
| |
| • |
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. |
|
