When you deal with gas or fluid, one thing you need to know is whether it is moving. And if so, how much? That’s where flow indicators and flow meters come in. They help you track flow. If you work with pumps, valves, or plant gear, this post will help you pick the right tool for the job.
What is a Flow Indicator?
A flow indicator is a small, smart tool that tells you if fluid or gas is on the move. It shows you that flow is there. Most times, it has a clear view port with a flap or ball that moves when the fluid flows.
Do you know Tecmak makes strong sight flow indicators that work well in tough spots—like hot lines, steam pipes, or high-pressure loops?
Use a Flow Indicator When:
- You want a fast check to see if flow is live
- You don’t need to track flow rates or total flow
- You’re in a low-risk zone or a test line
- You want a low-cost fix
What is a Flow Meter?
A flow meter does more. It tells you how fast the fluid flows and how much goes through a point. It shows flow in real-time. Most meters show flow in liters per minute, cubic meters per hour, or GPM. Tecmak’s range of flow meters work with gas, steam, oil, and more and they hold up well in plant use, labs, and even harsh zones.
Use a Flow Meter When:
- You need full flow stats
- Your line links to a control loop
- You plan to log or send flow data
- You need tight checks for cost or quality
Main Differences
| Aspect | Flow Indicator | Flow Meter |
| Shows Flow? | ✅ Yes | ✅ Yes |
| Tells Rate? | ❌ No | ✅ Yes |
| Power Need | ❌ No | ✅ Some do |
| Cost Range | 💰 Low | 💰💰 Higher |
| Use Case | Checks, start-ups, low-risk zones | Big plants, tight specs, cost control |

How to Choose a Flow Indicator?
Ask yourself these three things:
Q. Do I need to know the flow speed or rate?
If yes—go for a flow meter.
Q. Do I just need to see if the flow is there or not?
Then, a flow indicator may be all you need.
Q. Do I have the space, power, and budget for high-tech tools?
If yes, meters are the way to go. If not, keep it lean with an indicator.
