To be on the safe side you could measure the actual distance and check the datasheet of the desired computer.
Sensors tend to work either on ANT+ or bluetooth which have easily 3m of range. In the case of indoor trainer, the speed sensor has to be on the rear hub and it works perfectly well.
Then when it come to accuracy with older device (like my fenix 5 plus manual mode), the best is set 2 marks 10mm apart , align the valve with the 1st mark and then count the number or rotation needed to reach the 10m. Or, align the valve, count 5 rotation, mark the valve @ rotation 5 and measure the distance.
Once you have the distance per rotation, add it to the sensor setup in the machine.
But, most of GPS equipped devices (fenix 5plus in mode auto or edge 530/130plus) will disregard the speed sensor data for 1K but would still count the number of rev. After that 1k, it give a message saying the speed sensor is calibrated and switch to speed sensor reading (useful in tunnel)
