Development history of target flowmeter? 

Target flowmeter is a kind of differential pressure flowmeter. It has been used in industry for decades.Electric and pneumatic target flow transmitters were developed in China in the 1970s.At that time, the force converter directly adopted the force balance mechanism of differential pressure transmitter, and this kind of flowmeter inevitably brought many defects caused by the force balance mechanism itself, such as easy drift of zero position, low measurement accuracy, poor reliability of lever mechanism and so on.Due to the drag of the force balance mechanism, many advantages of the target flowmeter itself have not been effectively played, so far, users have not eliminated the bad impression of the old target flowmeter. 

Why the target flowmeter is widely used, is there any limit for measurement? 

The target type flowmeter is simple in structure, which is to open a hole in the measuring pipe and load the force sensor into a fixed line. Within a certain Reynolds number range, as long as the fluid flow produces a force on the target plate, it is almost free from any conditions. 

How does the target flowmeter force sensor work? 

Early power converter directly USES the force balance mechanism of differential pressure transmitter, the mechanical linkage meter when using poor reliability has been gradually withdraw from the market, most of the existing target flowmeter using strain chip force sensor, namely in a circle, square, etc.) elastomer with a pair of strain gauge of huis bridge type circuit, sensor fixed on the measuring tube is connected to the target (choke) of rod and target, fluid of elastomer trace target plate produced by the force deformation, and break the balance of bridge output a set of electrical signal after amplification of MCU, integrating, namely get traffic.The new capacitive force sensor USES high technology material and components.

Target flowmeter measuring accuracy up to 0.2%? 

The measurement accuracy of target flowmeter can reach 0.2% relative measurement error. 

Is there any influence of vibration on the measurement of target flowmeter? 

The application data of target flowmeter in recent years show that the vibration has no great influence on it and pulsating flow can be measured in a certain range. 

Can target flowmeter measure small flow rate? 

The target type flowmeter can be used when the small flow rate is difficult to measure.
