This wireless flow sensor system includes the flow sensor, RF transmitter and RF receiver. Installation no longer requires expensive trenching, drilling, or digging to install power or I/O wiring. The self powered flow sensor / transmitter unit performs flow measurement and scaling. The unit transmits a total flow value via an RF transmitter.The total flow value is received approximately every 4 seconds. A pulse output can then be programmed for different volume units and pulse widths.
 
228PV Wireless Flow Sensor
The four-bladed impeller design is rugged, non-fouling and does not require custom calibration. Coupled with the proprietary patented digital detection circuit, the sensor measures flow rate from 1fps to over 20fps regardless of conductivity or turbidity of the liquid. The flow sensor generates a frequency which is proportional to flow rate. An integral micro controller computes the impeller frequency using the appropriate K factor and Offset values which is then translated to flow rate. By means of integration, the volume total is calculated. The output signal is a scaled output pulse that can be scaled for various units and pulse widths. An internal lithium battery provides power for the flow sensor/transmitter.
 
Wireless 350T RF Transmitter
The 350T transmitter operates at approximately 900MHz at a power level which requires no F.C.C. licensing. The transmitter is powered using an internal lithium battery and is encapsulated to ensure moisture resistance.
 
Wireless 350R RF Receiver
The 350R receiver is powered using an external AC or DC power supply. The wireless receiver receives the scaled total from the transmitter. Further scaling and unit conversion can be programmed into the receiver. The optically coupled scaled pulse output emulates a dry contact closure to ensure interfacing into various types of controller inputs. Antenna options include BNC cables, BNC feed through headers, and BNC right angle adapters.
