Frequently Asked Question

1: How is turbidity measured in this device?

It uses infrared absorption and scattering technology to minimize color interference, ensuring accurate turbidity readings in NTU (Nephelometric Turbidity Units).

2: What if the device fails to communicate via RS485?

If it is not communicating well, please confirm proper wiring and terminal resistance, matching baud rate, address, and parity settings on your MODBUS controller, sensor is powered and functioning.

3: Where is Online Turbidity Meter FM-OTM-A100 commonly used?

It’s ideal for water treatment facilities, sewage and wastewater plants, industrial processing, farming and aquaculture, environmental monitoring stations.

4: What is the accuracy of this meter?

The unit offers accuracy of ±2%, with a resolution better than ±5% depending on sludge homogeneity.

5: What maintenance is required?

Maintenance usually includes regular sensor cleaning to remove biofilm or debris, calibration checks using standard solutions, verifying optical window clarity and system diagnostics.

6: How does Fison online turbidity meters work?

Our Online Turbidity Meters operate based on the nephelometric method, where a light beam is directed into the water and a sensor measures the light scattered at a 90° angle. The amount of scattered light correlates with the concentration of suspended particles.
