Analog gas flow meters specifically refer to a type of flow meter that outputs analog signals. The main function of a flow meter is to measure volumetric flow rate or mass flow rate and convert it into an electrical signal output, facilitating flow monitoring and control.
There are four types of flow meter signal outputs: analog signal output, frequency signal output, digital signal output, and switch signal output.
Common Analog Signal Types for Flow Meters:
Flow meters are configured with analog signals, typically 4-20mA, 0-10mA, 0-5V, 1-5V, 2-10V, etc.
The analog output corresponds to a percentage of the flow rate. That is: for a 0-10mA output, the current zero point is “0”; for a 4-20mA output, the current zero point is 4mA, and the current range is 16mA. To improve the resolution of the flow meter’s analog output, users should appropriately select the flow meter’s range. Sino-Inst has calibrated all parameters of the analog output at the factory. Generally, users do not need to adjust them.
Benefits of Analog Gas Flow Meters
Analog signals are continuously varying signals that represent flow rate through physical quantities such as voltage and current. In Analog Gas Flow Meters, the flow rate is typically measured directly by measuring the voltage or current changes generated by the gas as it passes through the flow meter.
Analog Gas Flow Meters have several significant advantages:
- Continuity: Analog signals are continuous in the time domain. That is, the signal magnitude changes continuously over time. This continuity ensures high accuracy when representing continuously changing physical quantities.
- Good Stability: Analog signals typically exhibit stable output characteristics. That is, under the same flow rate, the output voltage or current signal magnitude remains relatively stable. This stability allows analog signals to maintain high accuracy during long-term measurement and transmission.
- Ease of Processing: Analog signals can be amplified, filtered, and converted by various electronic devices to meet different application requirements. This makes analog signals widely applicable in the field of flow measurement.
Common gases: natural gas, nitrogen, argon, hydrogen, helium, oxygen, CO2, biogas, compressed air, etc.
