Product Description:

CAFS5032 medical flow sensors are made of microelectromechanical system (MEMS) flow sensing chips, which are suitable for various purposes of cleaning and relative Dry small flow gas measurement and process control, unique packaging technology enables theproduct to meet different range of flow measurement, to ensure high sensitivity, high reliability,High stability and low cost.It is based on a MEMS flow sensing unit and a high-precision digital processing and calibration circuit (MCU). The integrated delta-sigma/D converter and the logic circuitry and MCU processor with internal calibration ensure that the sensing signals are efficiently acquired in real time and that accurate flow signals are obtained and performed internally The corresponding compensation algorithm is processed, so there is no need to do any external calibration compensation to ensure high-precision flow output; Friendly digital output communication mode,Users can easily get the corresponding data information for communication; The range of applications is very wide.

1. RS485 communication
The communication mode of the flowmeter is RS485, and there are two protocol modes: (the factory default is B mode)
A. Factory calibrated communication protocol, which is a stand-alone communication protocol;
B. Modbus protocol is a multi-machine communication protocol.
The settings are:
Baud rate 9600 (A protocol) / 9600 (B protocol);
Data bits 8;
Stop bit 1;
Checksum/flow control none.
The communication protocol is as follows: Modbus communication protocol of the upper computer of the CAFS5000 series gas mass flow meter
