Description

TECHNICAL FIELD

[0001] The utility model relates to flowmeter technical field, concretely is a kind of integrated flowmeter wiring structure. BACKGROUND

[0002] Mass flowmeter is composed of sensor and transmitter. Sensor is directly connected with pipeline, wherein there are two groups of sampling coils and a group of driving coils. Signal line connects the three groups of coils through internal wiring of sensor and is connected with outlet bolt, then is connected with transmitter, and driving signal and sampling signal are transmitted to transmitter for processing. Transmitter processes signal to obtain flow rate, density and other parameters and communicates with external world. According to the installation mode of sensor and transmitter, mass flowmeter can be divided into two types: integrated mass flowmeter with transmitter and sensor directly connected together; and split type flowmeter with transmitter and sensor independently installed, and signal of sensor is transmitted to transmitter through cable.

[0003] Whether integrated mass flowmeter or split type flowmeter, signal needs to be led out from inside of sensor, and then connected with transmitter through appropriate mode. To realize the connection of sensor and transmitter, there are following problems: first, sensor must isolate measuring mechanism from external world to ensure that vibration of measuring mechanism is not disturbed. Because hole allowing signal line to pass through must be reserved on some components of sensor, so the sealing property of sensor is damaged. Second, because necessary measures and additional parts must be taken in subsequent manufacturing process to ensure the sealing of sensor, so process complexity and cost are increased. Third, because some parts for realizing the function of mass flowmeter are added, so the installation size of mass flowmeter is increased, and larger installation space is required. Fourth, because parts for realizing the function of mass flowmeter are added on sensor, so the symmetry of sensor is damaged, and sensor is not beautiful. Therefore, a kind of integrated flowmeter wiring structure with better sealing property of sensor and convenient welding is designed to solve the above problems. SUMMARY
