I search about mechanical level indicator to be pipe mounted. Can anyone recommend company products this type? can send us the name?

You need to be a bit more specific about what you are trying to measure. Send me an e-mail and I may be able to help

Usually one starts with
- purpose (school project, indication, control,)

- the medium (water, fuel oil, glycerin, etc),
- its characteristics (clean, viscous, slurry, foam, corrosion potential)
- depth of level needed (1 meter or 100m?)
- operating conditions (pressure, temperature, hazardous area restrictions),
- vessel situation (mounting access),
- other requirements (local indication, electrical signal, pneumatic signal, digital signal, etc).

rather than physical mounting, first.

Let's assume, in the absence of any particularly useful information, that you are dealing with liquids.

1) A bubbler level system is a pipe that goes into a vessel of liquid. A differential pressure regulator regulates the pressure to maintain a constant low flow, just enough to get a stream of bubbles out the bottom of the pipe. Note this is a differential regulator.

The pressure in the pipe will match the head of the liquid. So the pressure in the pipe, downstream of the regulator is measured with a pressure instrument, as an indication of the level.

If you search this forum for 'bubbler', there are various other posts that describe the construction of the tube with a V notch, and pros and cons of such technology.

In the USA, Siemens/Moore makes a differential regulator. The pressure sensor can be anyone's pressure transmitter.

2) Bypass sight indicators are pipes mounted to a low port (and usually a high port as well) on a liquid tank. A magnetic float rises and falls inside the pipe with the liquid level (assuming it doesn't 'stick' or 'hang up' or fail to float because its boyancy is insufficient to float it in the liquid the operator filled the tank with).

A series of flags is mounted to the exterior of the unit. The flags have one color, like white, on one side, another color, like orange, on the othe side. The flags flip or rotate on their axis pivots to visually indicate the level where the color changes from white to orange.

In the USA, Kobold, Gems, Penberthy, Barksdale, KSR Kuebler & a dozen others whose names don't come to mind immediately make these.

Both bubblers and bypass sight indicators are pipes themselves.

Of course there are about a dozen other level technologies which can have electronic level indicators mounted to a pipe, but the level sensor is mounted elsewhere.

I need to clear that the pipe starts from the bottom of Scale inhibitor tank, and it goes down vertical for a distance then goes horizontal. The level indicator should mount in the horizontal portion.
