What is the difference between gas turbine flow meter and liquid turbine flowmeter?

The main difference between the gas turbine flow meter and the liquid turbine flow meter lies in the measured medium. Below we mainly compare the gas turbine flowmeter
and the liquid turbine flowmeter from the product usage and product characteristics:

Product use of gas turbine flowmeter:

 

Gas turbine flowmeters are used in petroleum, chemical, electric power, metallurgy, urban gas supply and other industries to measure various gas flows. It is currently the
first choice for oilfield and urban natural gas transmission and distribution metering and trade metering. It is mostly used for low-to-medium flow rate gas metering.

 

Product features of gas turbine flowmeter:

 

1. Accuracy, generally up to ±1.5%R, ±1.0%R;

2. Low starting flow, small pressure loss, good anti-vibration and anti-pulsating flow performance;

3. A rectifier with excellent rectification performance reduces the rigidity requirements of the front and rear straight pipe sections;

4. Independent movement design, good interchangeability and convenient maintenance.

Product use of liquid turbine flowmeter:

 

Liquid turbine flowmeter is suitable for measuring water, diesel, methanol and other non-impurity, non-corrosive liquids. It is widely used in petroleum, chemical, metallurgy,
textile, paper, environmental protection, food and other industrial sectors and municipal management, water conservancy construction, and river dredging. Metering and
control systems in other fields. Liquid turbine flowmeters equipped with hygienic quick couplings can be used in the pharmaceutical industry.

 

Features of Liquid Turbine Flowmeter:

 

1. Wide measuring range (range ratio of 1:20 above DN10mm);

2. Multi-signal output, suitable for total measurement and connection with computer, strong anti-interference ability;

3. Accuracy, generally up to ±1%R, ±0.5%R, accuracy type up to ±0.2%R;

4. Good repeatability, short-term repeatability can reach 0.05%~0.2%;

5. It is suitable for large-caliber measurement, with low pressure loss and low price. It can be taken out continuously, and it is convenient to install and maintain.

 

The price of a gas turbine flowmeter is generally several times that of a liquid turbine, mainly because of the difference between the production cost and the calibration cost.
