1. Brief introduction of nitrogen turbine flow meter

Nitrogen turbine flow meter is a new generation of high-precision and reliable gas precise measuring instrument, which is self-developed and integrates temperature, pressure, flow sensor and flow totalizer with the advanced technology of flow instruments at home and abroad.

Nitrogen turbine flow meter is widely used in urban pipeline gas metering, industrial gas metering, gas regulating station metering, energy management and non corrosive gas metering or flow control and other occasions.


2. Advantages of nitrogen turbine flow meter

1. LCD. Intelligent liquid crystal meter head which can display temperature, pressure and flow at the same time.
2. Power supply uses external power 24v abd 3.6v lithium battery.
3. The impeller life is durable and has strong impact resistance.
4. The flange material is made of all 304 stainless steel, which has good processing performance, high temperature resistance and is not easy to rust after long-term use.

Vortex flow meter (gas/liquid)
Vortex flow meter is used to measure the volume flow of gas, steam or liquid, the volume flow of standard condition or the volume flow of mass flow. It is mainly used for flow measurement of industrial pipeline medium fluid, such as gas, liquid, steam and other media.

Thermal mass flow meter
Suitable for: gas with small flow, pure/single gas
Wide range: 1:100
High precision: ±1.5%. Without temperature and pressure compensation, the mass flow rate and standard volume flow rate of the gas can be obtained.
Material: 304 stainless steel Sensor and 316L Probe
Standard configuration: LCD with backlight, 4-20mA, RS485, 220v +24v dual power supply.
Working temperature: -40℃-220℃
Pressure: 0.6-4.0Mpa

Packaging and Shipping

Each of our flow meter after factory calibration, according to different size do packaging, usually, below 100 mm flow meter will be used in fine carton packaging, above 100 mm flow meter will be used free of wooden case packaging. We will ensure that each flow meter, safe to reach your hands.
