Digital Propane Flow Meters

Digital LPG/Propane flow meter

A propane flow meter refers to a flow meter that can measure the volume or mass flow of propane gas. Also often called LPG gas flow meter.

Featured Inline Propane Flow Meter

Propane is also generally referred to as liquefied petroleum gas (LPG). So what is the difference and connection between propane and LPG? Next, let’s take a look together.

Propane VS LPG

Because propane is one of the main components of liquefied petroleum gas.

Propane is pure, and liquefied petroleum gas is a mixture.

LPG is a by-product obtained during the catalytic cracking and thermal cracking of crude oil in refineries.

The main source of commercial LPG is the processing and refining of natural gas and oil. The raw materials usually contain excessive amounts of propane and butane. To prevent these two substances from condensing in the high-pressure exhaust pipe, they must be removed.

In the petroleum refining process. LPG is collected by titration from the dissolved crude oil mixed with a lighter specific gravity. At the same time, it can also be produced by the molecular fission of heavy hydrocarbons. Therefore, LPG is considered a subsidiary product. Its exact composition and characteristics usually vary from source to source.

Precession Vortex Gas Flowmeter for LPG/Propane measurement

Precession vortex flowmeter is a new type of gas flowmeter. It can be used for the measurement of natural gas, propane, air, nitrogen, and other gases.

Precession Vortex Gas Flowmeter, like a vortex flowmeter, is a velocity flowmeter. The cost performance of the intelligent precession vortex flowmeter is higher than the vortex flowmeter. The intelligent precession vortex flowmeter can only measure gas. Precession Vortex Gas Flowmeter can be made into an integrated temperature and pressure compensation. And can measure various gases. Such as compressed air, oxygen, biogas, natural gas, coal gas, etc.

Precession Vortex Gas Flowmeter reference price: DN50, USD 600.00/pc.

Advantages of Precession Vortex Gas Flowmeter.

  • No mechanical rotating parts, not easy to corrode, no maintenance required for long-time work;
  • It can be used on the occasion of medium and high flow rate gas;
  • The process installation conditions are not harsh, and the upstream and downstream straight pipe sections of the instrument can be greatly shortened compared with the orifice flowmeter;
  • The measurement accuracy of the system can meet the current trade measurement requirements (≤2%);
  • The flow measurement range is wide (Qmax/qmin=15~20″>). It can work effectively in some small flow areas that the orifice flowmeter cannot reach;
  • Small size and lightweight, it is more convenient for offline calibration;
  • The measurement signal can be displayed on the spot or transmitted remotely as required;

Why is Precession Vortex Gas Flowmeter the right Propane flow meter?

Before that, people would use vortex flowmeters to measure propane.
Although the precession vortex flowmeter and vortex flowmeter are all fluid vibration flowmeters. However, the precession vortex flowmeter has the following advantages:

  1. The generated vortex signal is stronger than that of a vortex flowmeter, so the lower limit Reynolds number is lower. When measuring gas flow, the lower limit flow rate can be as low as (1.5~2) m/s.
  2. Because the vortex signal generated by the flowmeter is stronger than that of the vortex flowmeter. It is less affected by the upstream choke than the vortex flowmeter. Therefore, the length of the upstream straight pipe is much shorter.
  3. The meter coefficient K is 1 to 2 times larger than that of the vortex flowmeter.

Liquid propane flow meter

Propane can be measured with a vortex flowmeter. If it is corrosive, it must be plated with PTFE, which can prevent corrosion.

Vortex-Shedding-Flow-Meter

Vortex shedding flow meter also called Vortex flow meter. Vortex shedding flow meter is suitable for measuring steam flow rate as well as liquids and gases.

Vortex shedding flow meter, easy installation, low cost, analog, and 4-20mA output. Pressure & temperature compensation can improve the sensor for more accurate measurement. Vortex shedding flow meter is suitable for measuring steam and various liquids and gases. When the fluid flows through the assembly line of the vortex flowmeter, a vortex is formed. The frequency of vortex shedding is directly proportional to the fluid velocity.

Vortex shedding flow meter reference price: USD 200-1500/pc.

Propane gas mass flow meter

Thermal Mass Flow Meter

Thermal Mass Flow Meter can directly measure the mass flow of various gases. Unaffected by changes in viscosity, density, temperature, or pressure.

A thermal Mass Flow Meter is a true mass flow meter. No temperature and pressure compensation is required. Thermal gas mass flow meters are designed based on the principle of thermal diffusion. Including natural gas, coal gas, liquefied gas, flare gas, argon, carbon dioxide and other mixed gas flow measurement.
