Toro TFS-100 1" TFS Flow Sensor

Hi, there! Thank you for your query about the Toro TFS-100 flow sensor. To connect this flow sensor to your controller, you'll need a flow interface module, such as the Toro TSM-4F. To install the flow sensor and master valve circuit, first, route the flow sensor wires into the controller cabinet. Then, connect the sensor wires to the flow-enabled expansion module, with the black wire to negative (–) and the red wire to positive (+), ensuring the correct polarity for proper operation. Lastly, if using the master valve circuit, connect one solenoid wire to the MV terminal and the other to either common terminal (C). You can refer to page 23 of the user manual for more details.
