PFS Series - Irrigation Flow Sensors
The Baseline PFS Series Flow Sensors have a unique low drag, a lightweight impeller design, and a specially engineered tee cavity and impeller placement to ensure smooth flow and precise performance at the lowest flow rates. Every Baseline PFS Series Flow Sensor is two-wire ready with a Flow biCoder built into the tee insert. Because a Flow biCoder is built into each flow sensor, every device comes pre-configured with the correct K and offset values. The PFS Series Flow Sensors are available in 1½” to 4” sizes.
Specification
Flow biCoders™
Features
- The Flow biCoder has true two-way communication using a 9-byte packet for commands and replies.
- The Flow biCoder is capable of self-identifying to the two-wire controller and will report pre-configured unique serial numbers and zone addresses.
- The Flow biCoder serial number is printed on the side of the decoder.
- Each Flow biCoder has 24 inches of 16-gauge PVC jacketed solid core wire to connect to the two-wire.
- Each Flow biCoder has 24 inches of 18-gauge PVC jacketed stranded core wire to connect to a pulse output flow meter.
- The Flow biCoder can be connected to flow devices with either 2 or 3 wires.
- The Flow biCoder has collision detection on the two-wire and is able to resend messages if a collision is detected.
- The Flow biCoder reads a minimum of a 5-millisecond low pulse at 200 hertz and a maximum of 200 pulses per second.
- The Flow biCoder is able to search for a flow meter.
- The Flow biCoder is able to run a pulse-output flow meter up to 1000 feet away.
- The Flow biCoder has a built-in amperage meter to accurately measure and diagnose flow meter electrical problems such as “no current,” “station short,” or “over current.”
Connection Requirements
- Use two-wire connectors that are DBR/Y or equivalent direct bury splice, made for full submersion and effectively seal moisture out.
- Make all connections per manufacturer’s specifications.
- Verify that no loose, unshielded wiring can touch the soil, water, or another copper conductor causing a leakage of current to the ground or a short circuit across wires.
- Make all splices inside a valve box.
- Mount all connections vertically to eliminate standing water inside the DBR/Y connector.
Flow Features in the Irrigation Controller Software
- Learn the flow for each zone
- Use flow data to maximize the number of zones the controller can turn on at once to help shorten your water windows
- In the event of unexpected high or low flow, automatically determine which zone is at fault and alert you without interrupting the rest of the watering cycle
- Protect your site from mainline breaks with configurable high and low flow shutdown settings
