7. Digital Output Measurements
The FS3000 continuously measures in operation.
The data is sent in byte packages. Each byte is followed by an ACK from the slave. The most significant bit (MSB) is transmitted first.
To read the data, the following command is sent to the FS3000.
After the START bit, the master device sends the 7-bit slave address followed by an eighth bit = 1 (READ). The READ bit indicates a transmission
from the FS3000 (slave) to master. See Figure 6.
The checksum used for data integrity is returned from the FS3000 followed by the two bytes of flow data.
The flow data is a 12-bit integer. Only the least significant four bits in the high byte are valid. See Figure 7.
