Flow meter turndown
WebA flow controller or flow meter’s turndown ratio is highly influenced by the device’s signal-to-noise ratio, which is a result of the type and quality of the sensor used, and the fluid dynamics of the flow measurement technology. For instance, many orifice-plate differential pressure-based flow measurement devices possess turndown ratios of ... WebA turndown of 10-to-1 implies that a typical flowmeter will operate properly from (say) 0.25 to 2.5 meters per second. Increasing the turndown to 100-to-1 implies the flowmeter will …

WebIf we look further, the 2500 l/m minimum flow and 7500 l/m maximum flow is correspond to the 3:1 turndown ratio. This is where the 3:1 turndown ratio is applied in our general practices. If we insist to have minimum … WebJul 14, 2009 · Everything I find online or otherwise states that orifice plates have a turndown of 3:1 for 1% uncertainty, 4:1 for 2% uncertainty, and 10:1 for 5-10% uncertainty. The DP transmitters we typically use have a turndown of 40:1. It seems to me that the turndown of the transmitter itself would be the limiting factor of the flow measurement.
WebIn this example, the turndown ratio would be 10:1. Another similar example would be a flow meter that has a minimum flow rate requirement of 2 GPM, and the maximum flow rate is 20 GPM. This also is a turndown ratio of … WebAdditionally, all Sierra's industrial thermal mass flow meters provide a wide turndown ratio, very low-pressure drop, no moving parts, application …

In flow measurement, the turndown ratio indicates the range of flow that a flow meter 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 least 10:1. Therefore the meter requires a turndown ratio of at least 10:1.
