Float & Board Level Gauge
Direct visual indication of tank level at a glance.
We measure the level — nothing else, all day.
Level measurement instrumentation is the whole business at APSAN INDIA Instruments — gauges, transmitters and float switches that track liquids and slurries across process tanks, built and engineered under one roof in Bhosari, Pune.

Level instrumentation, made in Pune
One trade, done properly
APSAN INDIA Instruments Pvt. Ltd. is a manufacturer, exporter and supplier based in MIDC Bhosari, Pimpri Chinchwad. The company designs and builds gauges, transmitters and float switches used to track liquids and slurries across process tanks and industrial equipment — with in-house fabrication, engineering and supply all run from a single Bhosari facility.
Because the workshop and engineering side sit under one roof, a buyer talks to people who actually build the instruments. The team helps size and select the right gauge, transmitter or switch for a given tank, translating operating conditions into a workable specification rather than leaving you to guess — and the support carries through to a complete, working solution rather than stopping at the sale.
The core product line
Indicate. Transmit. Switch.
Everything you need to read and control tank level for a wide range of liquid applications — off the shelf or built to your specification.
Visual indication
Tubular Level Gauge
Graduated tube reading of level for clean liquid service.
Continuous output
Level Transmitter
Continuous electronic measurement for control panels and remote monitoring.
Point-level control
Top Mount Float Switch
Drops in from the top of the vessel — ideal where the sides are inaccessible.
Point-level control
Side Mount Float Switch
Threads or flanges into the tank wall at the exact height a level needs catching — for high/low alarms and pump control.
Slurry & liquid
Float Level Sensors
Float material and range matched to the fluid for accurate, long-lasting results.
Built to your specification
Beyond the standard catalogue, APSAN manufactures to client drawings and process requirements — with choices around material of construction, pressure and temperature ratings, measuring range, and mounting or flange connections. A fit for OEM and custom orders alongside off-the-shelf supply.
Why buyers choose APSAN
The details that separate reliable from cut-corner
Keeping fabrication and engineering under one Bhosari roof lets the company control the things that matter in level instrumentation.
01
Accuracy that holds up
Float, range and reading method matched to the actual fluid — so the reading stays true in day-to-day service.
02
Durable construction
Corrosion-resistant, correctly rated builds rather than the cheapest usable material — stainless steel for aggressive media.
03
Coordinated work
Consistency comes from work that stays aligned between the drawing and the shop floor.
04
Technical team that builds
Quick responses and application advice from the people who actually make the instruments — not a sales desk.
Inside Bhosari
Workshop, engineering & test
Fabrication, engineering, a water test tank and dispatch — all in one facility.

Level instrument FAQs
What is a float and board level gauge and how does it work?
It gives a direct visual indication of tank level: a float rides on the liquid surface and its movement is shown against a graduated board, so you can read the level at a glance. It's one of the standard reading methods APSAN manufactures for a wide range of liquid applications.
What is the difference between a top mount and side mount float level switch?
A top mount float switch drops in from the top of the vessel and suits tanks where the sides are inaccessible, or where a single point needs monitoring from above. A side mount switch threads or flanges into the tank wall at the exact height a level needs to be caught, which is useful for high- or low-level alarms and pump control.
Which level gauge is suitable for corrosive liquids in and around Pune?
Where the medium is aggressive, stainless steel and other corrosion-resistant builds are the standard choice — for chemicals, slurries and outdoor tanks — so the wetted parts hold up rather than pitting over time. The material of construction is set against your actual service conditions as part of APSAN's build-to-spec route.
How do I select the right level indicator for my tank?
Start with the process: the medium, operating pressure and temperature, the measuring range and the mounting position all drive the choice. It helps to have vessel drawings, the operating range and the medium in hand, and APSAN's technical team will translate those conditions into a workable specification.
Can level gauges be used for both liquids and slurries?
Yes — the instruments cover both liquids and slurries. Matching the float material and range to the fluid's density and viscosity is part of getting an accurate, long-lasting result.
What is a level transmitter and how does it measure liquid level?
A level transmitter converts the tank level into a continuous electronic output for control panels and remote monitoring. It's often specified together with a float-and-board or tubular gauge on the same tank so you get both a visual reading and a continuous signal.
Do you manufacture level instruments as per client drawings?
Yes. Instruments can be built to client drawings and process requirements — with choices around material of construction, pressure and temperature ratings, measuring range, and mounting or flange connections — which makes APSAN a fit for OEM and custom orders alongside off-the-shelf supply.
