A meter counter is an important feature on many sewer camera systems because it tracks how far the camera has traveled inside the pipe. When the meter counter stops working, it can make it difficult to locate defects, estimate distances, or accurately document inspections.
The good news is that most meter counter problems are caused by a faulty connection, damaged wiring, or a failed component inside the reel, and can often be repaired without replacing the entire system.
This guide explains the most common causes of meter counter issues and how to fix them.

Meter Counter Not Displaying Distance
If the distance remains at zero or does not change as the cable moves, the counter may not be receiving a signal.
Common causes:
- Damaged meter counter circuit
- Loose wiring connection
- Faulty footage counter board
- Internal reel connection issue
Solutions:
- Check wiring connections inside the reel
- Inspect the meter counter board
- Test the circuit using a multimeter
- Replace the faulty component if necessary
A non-responsive counter is often caused by a wiring or circuit issue rather than the display itself.
Inaccurate Distance Readings
If the meter counter works but the displayed distance is incorrect, the measurement system may not be tracking cable movement properly.
Common causes:
- Slipping cable
- Worn measuring wheel
- Damaged counter circuit
- Calibration issue
Solutions:
- Inspect the measuring mechanism
- Verify the cable moves smoothly through the reel
- Check the counter circuit for continuity
- Replace worn components if needed
Inaccurate measurements can affect locating and reporting accuracy.
Meter Counter Will Not Reset
Some users experience a counter that continues counting but will not return to zero.
Common causes:
- Faulty reset button
- Counter board malfunction
- Internal control issue
Solutions:
- Restart the system
- Test the reset function multiple times
- Inspect the counter board
- Replace the faulty board if necessary
If the counter records distance normally but will not reset, the issue is often isolated to the counter board.
Meter Counter LED Not Working
Many meter counters include an LED indicator light.
Common causes:
- Failed LED
- Damaged counter circuit
- Power delivery issue
Solutions:
- Check power connections
- Inspect the meter counter board
- Replace the LED or counter assembly if necessary
If both the LED and counter fail at the same time, the issue is usually in the circuit board.
Damaged Wiring or Circuit Board
The meter counter relies on wiring inside the reel to transmit signals.
Common causes:
- Broken wires
- Corrosion
- Loose connectors
- Damaged circuit board
Solutions:
- Inspect visible wiring
- Test continuity with a multimeter
- Repair or replace damaged wires
- Replace the circuit board if needed
Wiring damage is one of the most common causes of meter counter failure.
Slip Ring or Reel Connection Issues
In systems with rotating reels, the slip ring helps transfer signals through the reel assembly.
Common causes:
- Worn slip ring
- Loose reel connection
- Signal interruption
Solutions:
- Inspect the slip ring assembly
- Check internal reel connections
- Replace worn components
Slip ring problems can affect both the meter counter and video signal.
How to Test the Meter Counter Circuit
A multimeter can help determine if the counter circuit is functioning properly.
Basic test:
- Locate the meter counter circuit board inside the reel.
- Place one multimeter probe on the counter board.
- Place the second probe on the corresponding wire connection.
- Test all three circuit points.
Results:
- All points show continuity ("beep") → circuit is functioning.
- One or more points fail continuity → wiring or board problem.
Meter counter problems often appear as:
- Incorrect distance readings
- Counter not resetting
- Counter not displaying distance
- LED indicator not functioning
Repair or Replace?
Repair is usually best when:
- The issue is isolated to the counter board
- Wiring can be repaired
- The reel and camera system still function normally
Replace components when:
- The circuit board has failed
- Multiple reel components are damaged
- Repair costs exceed replacement costs
Most meter counter issues can be repaired without replacing the full sewer camera system.
Key Takeaway
If your meter counter is not working, the most common causes are:
- Damaged meter counter circuit board
- Broken wiring
- Faulty reset function
- Slip ring issues
- Loose reel connections
Testing the counter circuit and inspecting reel components can usually identify the problem quickly.
Frequently Asked Questions
1. Why is my sewer camera meter counter not counting?
This is usually caused by a faulty counter board, damaged wiring, or a reel connection issue.
2. Why is the distance reading inaccurate?
The measuring system may be worn, slipping, or improperly calibrated.
3. Can a bad slip ring affect the meter counter?
Yes. Slip ring failures can interrupt the signal used by the meter counter.
4. Why won't my meter counter reset?
The reset button, counter board, or internal electronics may be faulty.
5. How do I test the meter counter?
You can use a multimeter to test continuity through the counter circuit and wiring.
6. Do I need to replace the entire reel?
No. Most meter counter issues can be repaired by replacing the counter board, wiring, or slip ring.
