1. What are the types of quality flow meters?
2. How to add density calculation when using an e h flow meter to detect wort?
When using an E+H flow meter to detect wort, the key is to accurately obtain the wort density and combine it with the flow meter measurement data for comprehensive analysis.
1. Obtain wort density 1 Using a densitometer for measurement: Select a densitometer with appropriate accuracy, clean and tidy it, slowly place it into the wort sample, and wait for the densitometer to stabilize before reading the value. For example, when using a common glass densitometer, it is necessary to ensure that the wort temperature is within the specified range, usually around 20 ℃, in order to obtain more accurate measurement results. 2. Convert the density at different temperatures: As the actual measurement temperature may not be the standard temperature, it is necessary to convert it through the density temperature coefficient. If the known wort density at 20 ℃ is ρ₂₀, the actual measured temperature is t, and the density temperature coefficient is α, then the actual density ρ=ρ₂₀ × (1+α × (
2. Integration of Density and Flow Calculation 1 Mass flow calculation: Based on the wort density ρ and the volumetric flow rate Qv measured by the flow meter, the mass flow rate is calculated using the mass flow formula Qm=ρ× Qv. For example, if the wort density is 1.05g/cm ³ and the volumetric flow rate is 10m ³/h, the mass flow rate Qm=1.05 × 10 × 1000=10500kg/h
2. Flow correction: Considering the possible impact of density changes on measurement accuracy, the measurement results of the flowmeter can be corrected based on density changes. If there is a significant fluctuation in density, the density can be regularly remeasured and the flow calculation results adjusted accordingly to ensure the accuracy of the measurement. By accurately measuring the density of wort and combining it with flow meter measurement data, the flow rate of wort can be more accurately grasped, providing reliable data support for the production process.
