1、 Usage and characteristics:

The LWGB turbine flow transmitter (hereinafter referred to as the transmitter) outputs a 4-20mA current signal and can be used in conjunction with the instrument or computer selected by the user to detect or control the volumetric flow rate in the measured pipeline. Explosion proof transmitters can be used in explosive gas environments, while corrosion-resistant transmitters can directly measure corrosive liquids. This transmitter has the characteristics of strong anti-interference ability, long service life, and easy operation and maintenance. It can be widely used in the fields of petrochemicals, metallurgy, papermaking, food, medicine, etc. It is an ideal instrument for flow control.

2. The transmitter is suitable for measuring stainless steel 1Cr18Ni9Ti, 2Cr13, and corundum (Al)₂O₃）A liquid made of hard alloy or engineering plastic UPVC or PP that does not corrode and has no impurities such as fibrous particles.

3. In addition to outputting 4-20mA current signals with remote transmission function, on-site display transmitters also have on-site digital display volume flow function, making it more intuitive and convenient for users to use.

2、 Model designation description:

3、 Main technical indicators:

1. Accuracy: Level 1.0, Level 0.5, Level 0.2
2. Environmental temperature -20~+50 ℃
3. Output signal: 4-20mA (two-wire system)
4. Output negative impedance 0-500 Ω
5. Power supply: DC 12V-24V

4、 Instrument selection:

1. Refer to the sensor selection method for transmitter selection.

2. The transmitter is mainly selected based on technical parameters such as actual flow range, nominal pressure, and measuring medium to determine the appropriate model of product.

3. If on-site display is required, it should be specified in the order, otherwise it will be considered as the basic type.
