Lets Get The Basic Of Detailed what is Exactly the Turndown Ratio?
Turndown ratio is a flow measurement term that indicates the range of specific flow meter, or meter type, is able to measure with acceptable accuracy. It is also known as rangeability. It is important when choosing a flow meter technology for a specific application. If a gas flow to be measured is expected to vary between 100,000 m³ per day and 1,000,000 m³ per day, the specific application has a turndown ratio of at 10:1. Therefore the meter requires a turndown ratio of at least 10:1. For example: if the meter had an advertised maximum flow of 2,000,000 m³ per day then the required turndown ratio would be 20:1.
The turndown ratio of each type of meter is limited by theoretical considerations and by practical considerations. For example, orifice meters create a pressure drop in the measured fluid proportional to the square of the velocity. Therefore the range of differential pressure can become too large and compromise accuracy. It can also create process problems such as hydrate formation, and in the case of measuring the discharge of a compressor, there is a limit to how much pressure loss is acceptable.
Turndown ratio is one of a number of considerations in choosing a meter type for an application. Some other considerations are price, maintenance cost, accuracy, the fluid type and the velocity of the flowing fluid.
The examples are here for gas flow, but the same meter types can be used on liquids as well, with similar turndown ratios. Note that meter manufacturers state their products' turndown ratios -- a specific product may have a turndown ratio that varies from the list below.
An orifice plate meter has a practical turndown ratio of 3:1. This means that if an orifice meter with a design flow rate of 200,000 m³ per day is installed, the flow range that the meter can measure accurately will be between 100,000 m³ per day and 300,000 m³ per day.
A turbine meter has a turndown ratio of 10:1. In the above application, the flow range that can be measured will widen to 60,000 m³ per day on the low side and 600,000 m³ per day on the high side.
Rotary displacement meters have a rangeability of between 10:1 and 80:1, depending on the manufacturer and the application. Diaphragm meters are considered to have a turndown ratio of 80:1.
Multipath ultrasonic meters often have a stated turndown ratio of 50:1. In our example application, the flow range expands to 28,300 m³ per day on the low side and 1,414,000 m³ per day on the high side.
In Case Of Measurement Systems Of Liquids and Gases-Pune and Its proven technology we are Able To Manufacture A Flowmeter with all Types For Min Of 1:50 and Upto 1:6000 with The Same Proven Accuracy
The Recent Flowmeter Technology By Measurement Systems Of Liquids and Gases Pune uses a Dual Turbine Flowmeter and Uses a Non Bearing Structure (Patent Under Process)which Can Offer a Very High Turndown Ratios.The Signals are Amplified and are Processed In Such a Way That The Turndown Ratio and Accuracy Do Not affect .The Flowmeter Manufactured are Very High Grade.
