1. What is the reason for the Anuba flowmeter displaying "anlog sat"?

The Anuba flowmeter displaying "anlog sat" (or similar to "Analog Saturation") usually indicates that the analog signal output has reached saturation, that is, the measured signal exceeds the range that the transmitter can handle. The following are specific reasons and solutions:

1. Signal out of range - fluid flow rate is too high, causing the differential pressure value to exceed the transmitters set range (such as the maximum differential pressure value being exceed). It is necessary to check whether the actual flow rate inside the pipeline exceeds the design range of the instrument. -The range parameter setting of the transmitter is incorrect, and the upper limit of the range needs to be recalibrated (usually adjusted through a HART controller or local button).

2. Electrical or sensor failure - differential pressure sensor is damaged or drifting, and the transmitter core module needs to be replaced. -Short circuit or abnormal grounding of the signal line, check the insulation and shielding layer of the cable for integrity

3. Abnormal fluid conditions - the probe is blocked or scaled by impurities, causing abnormal increase in differential pressure signal. The probe needs to be cleaned (using a blowing device or disassembling and cleaning after shutdown). -Fluid gas-liquid two-phase mixing or pulsating flow causes instantaneous pressure shock. Need to optimize installation location or add buffering devices. Processing procedure: 1 Check the current flow value: Compare the process parameters with the instrument nameplate range to see if they match. two Calibrate transmitter: Reset range through standard interface or resto

2. What is the working principle of the Annubar flowmeter? The working principle of the Annubar flowmeter is based on the fundamental laws of fluid dynamics, which calculates the flow rate by measuring the pressure difference formed when the fluid flows in the pipeline. Specifically, throttling element and pressure difference: When fluid fills the pipeline and flows through the throttling element inside the Annubar flowmeter, the flow velocity will sharply increase at the throttling element due to pipeline contraction, resulting in a decrease in static pressure. This change creates a significant pressure difference before and after the throttle component. Measurement and Calculation: The Anuba flow meter measures the pressure difference between the dynamic pressure upstream of the throttling element and the static pressure downstream, and calculates the flow rate using the flow continuity equation and Bernoulli equation. These two equations ensure the stability and repeatability of the measurement. Scope of application: The Annubar flowmeter is suitable for pipeline diameters ranging from DN20 to DN12000, particularly for flow measurement of liquids, fuel gases, steam, and gases in industrial production, such as fuel transportation and energy efficiency monitoring. Design Theory and Performance: The design theory of Ayuyu Niuba flowmeter is based on Bernoullis liquid deficiency equation, and its performance complies with JJG64090 regulations, which can accept standard inspection a
