Why Does A Magnetic Flow Meter Need Grounding?
Your mag meter suddenly shows erratic readings – did you check the grounding? Poor grounding causes 50% of all mag meter failures in the field. Magnetic flow meters require grounding to complete the electrical circuit for accurate measurement. Without proper grounding: 1) Stray voltages distort the weak flow signal (typically 1-10mV), 2) Electrical noise interferes […]
What Is the Measuring Range of Electromagnetic Flow Meter?
Recently, a water treatment plant lost thousands in revenue due to improper flow meter sizing. They didn’t understand their meter’s measuring range capabilities. Electromagnetic flow meters typically have a measuring range of 1:100, meaning they can measure from 0.1 to 10 m/s flow velocity. The actual flow rate range depends on the pipe diameter. Electromagnetic […]
What Causes Errors in a Magnetic Flow Meter?
Your mag meter was working perfectly yesterday – why is it showing erratic numbers today? Small installation oversights cause 80% of accuracy issues. Magnetic flow meter errors stem from: 1) Improper grounding (50% of failures), 2) Partially filled pipes (air bubbles disrupt readings), 3) Electrode coating (insulating buildup blocks signals), 4) Uncalibrated zero point, 5) […]
How Do I Reset My Electromagnetic Flow Meter?
Did your mag meter suddenly stop giving reliable readings? Before you reset, know this: factory resets erase ALL custom settings. To safely reset an electromagnetic flow meter: Power off, hold both arrow buttons while powering on, wait for "FAC" display (3-5 sec), press Enter to confirm, then re-enter basic parameters (pipe size, units, K-factor). Avoid […]
