How to choose a Hydrogen flow meter? Hydrogen is a valuable and widely measured industrial gas. Custody transfer metering is a very important feature of hydrogen flow measurement.

Common gas flow meters include thermal mass flow meters, vortex flow meters, precession vortex flow meters, and gas ultrasonic flow meters. How to select a hydrogen flow meter? Next, we will discuss in detail.

Characteristics of hydrogen

Hydrogen (chemical formula H2) consists of two hydrogen atoms, which is colorless, tasteless, odorless, non-toxic, and flammable. With a molecular weight of 2, and a specific gravity of 0.0695, hydrogen is considered the lightest gas, more than 14 times lighter than air (mv=28.8).

Hydrogen is very flammable. Under normal pressure, a mixture with a hydrogen content of 4.0% to 74% can be flammable. Since the minimum ignition energy of hydrogen (0.02mJ—one order of magnitude smaller than the minimum ignition energy of hydrocarbons) is very small, strict precautions must be taken to prevent leakage.

The most preferred hydrogen flow meter

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

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.

Mass flow measurement of hydrogen

At present, the Coriolis mass flowmeter and thermal gas mass flowmeter are the most reliable and the most reliable hydrogen flow measurement applications. Both of these are flow meters for direct mass flow measurement, and neither have movable parts and have a large range. The fluid contact surface is made of 316L, which improves the durability and safety of field application.

The sensors of Coriolis mass flowmeter and thermal gas mass flowmeter are all welded. Because the pressure sensor interface and temperature sensor are not required to correct the flow reading to the volume flow under the standard state. Therefore, the system pipe joint used Be reduced to a minimum.

The sensor connection method has flange connection, flange to clamp connection, thermal gas mass flowmeter can also provide large pipeline plug-in connection.

Coriolis mass flowmeters and thermal gas mass flowmeters can provide up to 0.5% accuracy due to their excellent detection technology, which has huge advantages in trade settlement and measurement.

These two types of flow meters have advanced measurement technology, good long-term application stability, and extremely low on-site maintenance costs. They are very popular measuring instruments.

The shortcomings of Coriolis mass flow meters: large pipe diameters are bulky, inconvenient to install, and extremely expensive to purchase. It is inferior to the thermal gas mass flowmeter in the small flow measurement characteristics.

Disadvantages of thermal gas mass flow meters: the high flow rate range is not as good as Coriolis mass flow meters. In order to accurately measure the hydrogen flow rate, it is necessary to use real flow calibration for the flow meter calibration.

Features of Hot Water Flow Measurement

What are the characteristics of hot water flow measurement? Let’s take a look.

1. The temperature of the measured fluid is not very high. When the flow meter is installed at the entrance of the heat exchanger body. The temperature of the fluid is generally not higher than 140°C. When the liquid outlet of the heat exchanger is installed, the flow temperature is lower.
2. The measured fluid pressure is not very good either. In order to send hot water to the highest floor in the building heating system, the pressure is sometimes higher. In the ground heating system, the highest pressure is 1MPa.
3. The pipe diameters vary in size. The smallest user, the pipe diameter is only DN20~DN40. The large-diameter flowmeter sometimes reaches about 1m.
4. Better cleanliness. Hot water is not as clean as tap water. The solid matter in the single water and its viscosity will not have a big impact on the general flowmeter.
5. Corrosive. Fresh water does not corrode the flowmeter. However, geothermal water has a certain degree of corrosion. Because it contains chloride ions and so on. Ordinary stainless steel materials are corroded, and the higher the fluid temperature, the more severe the corrosion.
6. The requirement for scope is not high. The pumps used in power plants (stations) to deliver hot water are generally combined in size. When the hot water supply is at its maximum, usually several large pumps are opened. When the heat supply is the smallest, generally only a small pump is turned on. The ratio of the maximum flow rate to the minimum flow rate is about 5~10. A flow meter for heat measurement of a single user. In the heating season, the flow measurement range of up to 10 can meet the demand. After the hot water valve is turned off, the market value of the flow should be 0.

Chemical flow meters types

Types of Flowmeters

The following will explain the flowmeters commonly used in the chemical industry.

1. Electromagnetic flowmeter. When a conductive fluid flows through an electromagnetic field, the velocity of the fluid can be obtained by measuring the voltage. The electromagnetic flowmeter has no moving parts and is not affected by the fluid. The accuracy of measuring conductive liquids when the tube is full is very high. The electromagnetic flowmeter can be used to measure the flow rate of the slurry fluid.
2. DP flowmeter can be used to measure the flow rate of most liquids, gases and steam. Positive displacement flow meter (PD). The PD flowmeter is used to measure the volumetric flow rate of liquid or gas. It introduces the fluid into the measuring space and counts the number of rotations. Impellers, gears, pistons or orifices are used to divert fluids.
3. Vortex flowmeter. The vortex flowmeter is to place a non-streamlined vortex generator in the fluid, and the speed of the vortex is proportional to the speed of the fluid to calculate the volume flow. The vortex flowmeter is suitable for measuring liquid, gas or steam. It has no moving parts and no fouling problem. The vortex flowmeter generates noise and requires the fluid to have a higher flow rate to generate the vortex.
4. Thermal mass flow meter. The fluid velocity is measured by measuring the increase in the temperature of the fluid or the decrease in the thermal sensor.
5. Coriolis flowmeter. This kind of flowmeter uses a vibrating fluid tube to produce a deflection corresponding to the mass flow rate for measurement.
6. Turbine flowmeter. When the fluid flows through the turbine flowmeter, the fluid causes the rotor to rotate. The rotation speed of the rotor is related to the speed of the fluid. From the average flow rate of the fluid felt by the rotor, the flow rate or total amount is derived.
7. Ultrasonic flowmeter. The propagation time method and the Doppler effect method are methods often used in ultrasonic flowmeters to measure the average velocity of the fluid. Like other speed meters, it is a meter that measures volume flow.

chemical magnetic flow meter

Electromagnetic flowmeters can measure the flow of general conductive liquids. It can also measure the volume flow of liquid-solid two-phase flow, liquid with high viscosity, strong acid, strong alkali, and salt liquid medium.

For chemical liquids, as long as they are conductive liquids, electromagnetic flowmeters can measure them.
