What are the components of a turbine flowmeter? The components of a turbine flowmeter

Turbine flowmeter is a commonly used flow measuring instrument, which has obvious advantages such as compact structure, intuitive and clear reading, high reliability, no interference from external power supply, anti-lightning strike, and low cost.What are the main components of a turbine flowmeter?

Components of a turbine flowmeter

Turbine flowmeter belongs to speed flowmeter, also called impeller flowmeter.The impeller flowmeter uses the proportional relationship between the rotational angular velocity of the impeller placed in the fluid and the fluid flow velocity, and measures the rotational speed of the impeller to reflect the volume flow of the fluid passing through the pipeline. It is one of the most accurate instruments in the flow instrument.Turbine flowmeter generally consists of the following five typical parts:

1. Body

The material of the meter body is generally steel or cast iron, and its two ends are connected by flanges.Small-caliber gauges 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 form a measuring assembly. Two high-precision stainless steel *self-lubricating bearings* supporting the turbine have a long service life.The turbine flowmeter can also choose an external lubricating oil pump to lubricate the bearing, but be careful not to overdo it.

3. Counter

The counter panel has the following important information:

(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 connection method.

4. Rectifier

The rectifier is used to make the fluid flow through the turbine flowmeter in a regular state, so as to eliminate the unfavorable influence of disturbance on the metering.High metering accuracy.

5. Magnetic coupling transmission device

The device separates the part of the counter in the atmosphere from the gas to be measured, and transmits the rotation of the measuring assembly to the counter.
