Why does the level reading on my IS Technologies Measuring Instruments change heavily and periodically?
If the level reading on your IS Technologies Measuring Instruments changes heavily and periodically, it may be due to a motor or alternator being installed. Try setting the velocity lower than the current setting value. Alternatively, move the level to a different position where it is not affected by the machinery.
What to do if the level on my IS Technologies ULM-1000C changes irregularly?
If the level on your IS Technologies Measuring Instruments changes irregularly, it may be due to a barrier within the ultrasonic range. Try setting the velocity lower than the current setting value or set the Detection Threshold Voltage lower than the current voltage. Also, check the sensor's bottom surface for any foreign debris or pollution.
How to fix an incorrect level reading in a sealed space with IS Technologies ULM-1000C?
If the level reading is incorrect in a sealed space when using IS Technologies Measuring Instruments, the pressure may be increased by gas generation. To resolve this, set the sound velocity according to the medium or install ventilation.
What to do if my IS Technologies ULM-1000C level shows only within blanking distance?
If your IS Technologies Measuring Instruments level shows only within the blanking distance, it could be due to protrusions in the nozzle of the reservoir. Check the nozzle's inside surface and the nozzle diameter, ensuring it matches the recommendation in the manual. You can also increase the blanking distance, but not beyond the highest level point.
