Composition of turbine flowmeter Posted by : admin / Posted on : Jul 16， 2021

Turbine flow meters are velocity flow meters, also called impeller flow meters. The impeller flowmeter uses the proportional relationship between the rotational angular velocity of the impeller placed in the fluid and the fluid flow rate. It reflects the volume flow of the fluid through the pipeline by measuring the speed of the impeller. One. Turbine flowmeter generally consists of the following typical five parts:
1. Body
The material of the watch body is generally steel or cast iron, and its two ends are flanged. Small-diameter meters also use threaded connections.
2. Measured components
There are precision-machined blades on the turbine, which together with a set of reduction gears and bearings constitute a measuring assembly. The two high-precision stainless steel permanent self-lubricating bearings that support the turbine ensure a long service life. Turbine flowmeter can also use external lubricating oil pump to lubricate the bearing, 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) Metering and minimum and maximum flow levels
(3) Product model and serial number
(4) Explosion-proof grade and mark
(5) The equivalent of the fluid corresponding to the low-frequency or high-frequency pulse and the wiring method.
4. Rectifier
The rectifier is used to keep the fluid in a regular state when flowing through the turbine flowmeter, so as to eliminate the unprofitable influence of the disturbance on the measurement. High measurement accuracy.
5. Magnetic coupling transmission device
The device separates the part of the counter in the atmospheric environment from the gas to be measured, and transmits the rotation of the measuring component to the counter.
