What are the components of a turbine flowmeter Posted by : admin / Posted on : Dec 20, 2019

Turbine flowmeter belongs to the speed type flowmeter. It uses the proportional relationship between the rotational angular velocity of the impeller placed in the fluid and the fluid flow rate. It measures the volumetric flow rate of the fluid passing through the pipeline by measuring the speed of the impeller. One of the accuracy meters. The following introduces the components of the turbine flowmeter in detail, and hope to help everyone.
Surface body
The material of the watch body is generally steel or cast iron, and its two ends are flanged. Small-caliber meters also have a threaded interface.
2. Measuring components
The turbine has precision-machined blades, which together with a set of reduction gears and bearings form a measuring component. Two high-precision stainless steel permanent self-lubricating bearings that support the turbine ensure a long service life of the component. The turbine flowmeter can also use an external lubricating pump to lubricate the bearings, but be careful not to overdo it.
3.Counter
The following important information is on the counter panel:
(1) Maximum working temperature and pressure:
(2) Measurement and minimum and maximum flow levels
(3) Product model and number
(4) Explosion-proof grade and mark
(5) Fluid equivalent and wiring method corresponding to low-frequency or high-frequency pulses.
4. Rectifier
The rectifier is used to keep the fluid in a regular state when it flows through the turbine flowmeter, thereby eliminating the unfavorable effect of the disturbance on the measurement. High metering accuracy.
5. Magnetically coupled transmission device
This device separates the counter part in the atmospheric environment from the measured gas, and transmits the rotation of the measuring component.
