Insertion Style Flow Sensors - 220 Series
- Pipe Size
1/2" to 4" - Flow Range
0.3...30 ft/sec - Temperature
from 0 to 105 °C - Pressure
Up to 400 PSI
The 220 Series sensors are specifically designed for installation in underground vaults that might be subjected to flooding. As the liquid flow turns the impeller, a low impedance 8V DC square wave signal is transmitted with a frequency proportional to the flow rate. This signal can travel up to 2,000 feet between the sensor and the display unit without the need for amplification.
