Vortex Flow Meter - Featured Design

Blade core technology

Using non-magnetic stainless steel, one-time processing and molding, for micro-signal interference and adjusting the precision of the friction coefficient of the blade surface, effectively increase and reduce the blade speed and adjust the measurement coefficient

CNC integrated precision machining

Impact resistance - The blades of the turbine are processed in one piece without contact, which has strong impact resistance, more balance, real flow performance, and better dynamic balance of operation. At low flow rates, no idling value is generated, which is your precise check.

One-piece processing and molding

Streamlined guide bearing

Stainless steel bearings are selected, with stronger impact resistance, effectively reducing fluid pressure loss and avoiding measurement errors

Blades without solder joints

High-precision machining, the blade is arc-shaped

Universal Welded Blade|Ordinary Probe Steel Material Guide Bearing

Blade solder joints are prone to embrittlement and fracture

The blade is flat, and the smoothness cannot measure the small flow on the side.

Poor impact resistance, easy to wear, small and too poor shunt, causing interference to measurement

Adopt communication socket connection design, strong and stable signal connection

Turbine Flow Meter | Working Principle

The working principle of the turbine flowmeter: the fluid flows through the sensor housing. Since the blades of the impeller have a certain angle with the flow direction, the impulsive force of the fluid makes the blades have a rotating torque. After overcoming the friction torque and fluid resistance, the blades rotate, and after the torque is balanced The rotating speed is stable. Under certain conditions, the rotating speed is proportional to the flow rate. Because the blade is magnetically permeable, it is in the magnetic field of the signal detector (composed of permanent magnets and coils), and the rotating blade cuts the magnetic field lines and changes periodically. The magnetic flux of the coil, so that electricity is induced at both ends of the coil
Pulse signal, which is amplified and shaped by the amplifier to form a continuous rectangular pulse wave with a certain amplitude, which can be transmitted to the display instrument to display the instantaneous flow and cumulative volume of the fluid. Within a certain flow range, the pulse frequency f is proportional to the instantaneous flow rate Q of the fluid flowing through the sensor, and the flow equation is: Q=3600×f/k
where:
f——pulse frequency [Hz];
k——The meter factor of the sensor [1/m], given by the checklist. If the unit is [1/L] Q=3.6×f/k
Q——Instantaneous flow of fluid (under working condition) [m3/h];
3600 - conversion factor.
The instrument coefficient of each sensor is filled in by the manufacturer in the verification certificate, and the k value is set in the matching display instrument, which can display the instantaneous flow and the cumulative total.
composition
Turbine flowmeters are velocity flowmeters, also known as impeller flowmeters. The impeller type flowmeter uses the proportional relationship between the rotational angular velocity of the impeller placed in the fluid and the fluid flow rate, and reflects the volume flow of the fluid through the pipeline by measuring the rotational speed of the impeller. one. Turbine flowmeters generally consist of the following typical five parts:
1. body
The material of the watch body is generally steel or cast iron, and the two ends are connected by flanges. Small-caliber gauges also use threaded interfaces.
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. Two high-precision stainless steel permanent self-lubricating bearings supporting the turbine ensure that the assembly has a long service life. The turbine flowmeter can also use an external lubricating oil pump to lubricate the bearings, 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 wiring method.
4. Rectifier
The rectifier is used to keep the fluid flowing through the turbine flow meter in a regular state, thereby eliminating the undesired effect of disturbance on the metering. High metering 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 assembly to the counter.
Instrument structure

1. The instrument installation adopts flange connection, threaded connection and clip-on type;

2. When installing, the liquid flow direction should be consistent with the direction of the arrow indicating the flow direction on the sensor shell, and the upstream straight pipe section should be ≥6DS, and the downstream straight pipe section should be ≥5DS (DS is the measured inner diameter of the pipe under test).
3. The sensor should be kept away from the external magnetic field. If it cannot be avoided, necessary measures should be taken;
4. In order not to affect the normal delivery of liquid during maintenance, bypass pipes should be installed outside the straight pipe sections at both ends of the sensor (as shown in Figure 4);
5. When the sensor is installed in the open air, please do a good job of waterproofing the amplifier plug;
6. The wiring method of the sensor and the display instrument should be selected according to the power supply of the amplifier.
