Featured Design

FRV vortex flowmeter: It adopts integrated molding processing design, applicable to pipe diameter: DN4 ~ DN200. It can effectively improve the unstable measurement of small flow and large flow. It is developed by the first general design of FGT. Measurement: diesel, gasoline, methanol, water, weak acid , Weak alkali and other liquids have built-in electronic adjustable accuracy, the measured medium, no impurities, low viscosity, no strong corrosive liquid. In line with design standards ATEX, IEC1709, CE, SGS, BSMI and other international certification indicators design, output types: 4 ~20mA, Pulse, RS485, support MODBUS RTU, NB-IOT protocol, and can be used with SMM cloud software to realize remote meter reading monitoring

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

Computing Processor Design:

Adopt multi-layer module function board design, any damage to any function board can be replaced independently

Adopt communication socket connection design, strong and stable signal connection

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.
