The flow meter sends out one pulse per a consumption unit by default. This pulse output can be connected to an external pulse counter to count the total consumption. The number of m per second are accumulated and indicated after one second. Pulse length depends on consumption rate. S430... - Page 37 10 Signal Outputs If the flow rate is higher than 50 m /s, l/s of ft /s, the S430 cannot output the pulses with default settings (one pulse per a consumption unit). In this case, you can set the pulse to 1 pulse per 10 consumption units or 1 pulse per 100 consumption units using by the S4C-FS service app or a connected display.

Questions and answers
Hi, why cant we measure flow at a vertical pipe by installing the flowmeter at a 90 deg angle?
The SUTO S430 flow meter cannot measure flow in a vertical pipe when installed at a 90-degree angle because the installation guidelines require a minimum insertion angle of 10 degrees. A horizontal installation (90-degree angle) is not permitted as it may affect measurement accuracy and sensor performance. Additionally, in vertical pipes, the flow direction must be from bottom to top for proper operation.
