Coriolis mass flow meters are widely used in Compressed Natural Gas (CNG) dispensers due to their high accuracy and reliability in measuring the mass flow of gases, such as natural gas, under varying pressure and temperature conditions. Here's how they are typically applied in CNG dispensers:
1. Precise Measurement of Gas Flow
- Coriolis meters directly measure the mass flow of CNG, which is a critical parameter in dispensing gas accurately. Since natural gas is often stored and dispensed under high pressure, it's important to measure it by mass rather than volume to ensure accurate fueling.
- The Coriolis principle works by detecting the deflection of a vibrating tube caused by the flow of the gas. The amount of deflection is proportional to the mass flow rate, providing high accuracy, even with fluctuating temperatures and pressures.
2. Compensating for Density Changes
- CNG dispensers need to adjust for density changes, especially since the temperature and pressure of the gas can vary throughout the dispensing process. Coriolis meters can measure the density of the gas along with the mass flow rate, enabling real-time compensation for density changes, which improves the accuracy of the volume dispensed.
3. Accurate Volume Calculation
- While traditional flow meters measure volume (which can be influenced by pressure and temperature), Coriolis meters directly measure mass flow and can use that data to calculate the volume accurately by applying real-time compensations for varying density.
4. Real-Time Data Transmission
- Coriolis flow meters can be connected to the CNG dispenser's control system via protocols such as HART or Modbus, providing real-time feedback on the mass flow rate, density, and temperature of the gas. This data allows the dispenser to automatically adjust for optimal filling and to comply with regulatory standards for fuel dispensing.
5. Enhanced Safety and Compliance
- CNG dispensing systems must be highly accurate and comply with industry standards, including those related to metering accuracy. Coriolis flow meters provide precise data for calibration and verification, ensuring that the dispenser is in compliance with local regulations for gas quantity and safety.
6. Durability and Maintenance
- Since CNG is a relatively clean gas, Coriolis flow meters have the advantage of lower maintenance needs. Their robust design makes them ideal for environments with varying temperatures and pressures, ensuring reliable performance over time in the harsh conditions often found at fueling stations.
Coriolis flow meters are a leading choice in CNG dispensers due to their reliability, accuracy, and ability to handle complex measurement conditions, ultimately improving the fueling experience and ensuring compliance with industry standards.
UNIQUE FEATURES OF ANDISOON MASS FLOWMETER
Mass flow meters are known for their high accuracy, wide measuring range and reliable performance, and have been successfully used in various industries over the past many years.
Unlike other instruments that are limited to measuring liquids at normal pressure and temperature, ANDISOON excels in measuring under challenging conditions, including high pressure, high viscosity, and high and low temperatures. For example, when measuring CNG (compressed natural gas), the difficulty lies in the high pressure. However, ANDISOON's sensors can withstand high pressures, allowing the necessary increase in flow tube thickness, allowing the transmitter to detect signals with greater sensitivity. Therefore, ANDISOON's mass flow meters specially designed for CNG gas dispensers have been widely used in the domestic market
In the field of cryogenics, Andisoon has developed a backflow meter and a liquid phase injection meter for LNG refueling stations, with a minimum temperature of -196°C.
In the field of process control, Andisoon has developed a micro-bend type mass flowmeter, with a maximum flow rate of up to 300t/h, widely used in petroleum, chemical and other industrial conditions.
