From the water sumps of a housing society to the solvent tanks of a Vatva chemical unit, Ahmedabad needs reliable level measurement. The right instrument depends on the tank, the liquid and how accurate the reading must be. As a level transmitter and hydrostatic level transmitter supplier in Ahmedabad, RB Automation supplies contact and non-contact level instruments and helps you pick the right principle.
Level Measurement Options We Supply
Hydrostatic level transmitter
The RB XSENSE RB21W hydrostatic level transmitter is lowered into the tank or well and measures the pressure of the liquid column above it. Because pressure rises with depth, the reading converts directly to level. It is simple, robust and well suited to water tanks, sumps, effluent pits and bore wells.
Magnetostrictive level transmitter
The RB XSENSE RBL01 uses a float moving along a probe to give a high-resolution continuous level reading, useful for process and storage tanks where accurate inventory matters.
Ultrasonic and laser level sensors
An ultrasonic level sensor measures from above without touching the liquid. A laser distance sensor gives a narrow beam for silos, chutes and narrow openings.
Level switches
Level switches give high, low or dry-run alarms to protect pumps and prevent overflow.
See the full family on our level sensing page.
Hydrostatic vs Other Level Transmitters
- Hydrostatic: lowest cost per point, immune to foam and vapour above the liquid, needs to be in contact with the medium.
- Magnetostrictive: high resolution, needs a clean enough liquid for the float to move freely.
- Ultrasonic: no contact, but foam, heavy vapour and obstructions can affect the echo.
- Laser: no contact and a tight beam, used for solids and narrow vessels.
How to Choose a Level Transmitter
- Tank or well depth and the measuring range you need.
- Liquid type: water, effluent, oil, solvent or slurry, and whether contact is allowed.
- Temperature, pressure and any foam or vapour in the tank.
- Mounting: top entry, side entry or lowered on a cable.
- Output: 4-20 mA to a PLC or display, or a switch contact for alarms.
Level Measurement in Ahmedabad
Chemical and dye units in Naroda, Vatva and Narol use level transmitters on raw material, reactor feed and effluent tanks. Pharma and food plants around Changodar and Moraiya need level control on process water and CIP tanks. Industrial estates, municipal projects and buildings across the city use hydrostatic transmitters on sumps, overhead tanks and bore wells, often with a level switch for dry-run protection.
Level Measurement Principles Compared
| Principle | Product | Contact with medium | Best for |
|---|---|---|---|
| Hydrostatic | RB XSENSE RB21W | Yes (submersible) | Water tanks, sumps, effluent pits, bore wells |
| Magnetostrictive | RB XSENSE RBL01 | Yes (float on probe) | Accurate level in process and storage tanks |
| Ultrasonic | Ultrasonic level sensor | No | Liquids that should not be touched, open tanks |
| Laser | Laser distance sensor | No | Silos, chutes, narrow openings, solids |
| Level switch | Level switch | Depends on type | High/low alarms and pump dry-run protection |
A Typical Level Application in Ahmedabad
A typical set-up in an industrial estate: an underground sump feeds an overhead tank through a transfer pump. A hydrostatic level transmitter in the sump and another in the overhead tank give a continuous 4-20 mA level to a small PLC, which starts the pump when the overhead tank is low and stops it before the sump runs dry. A separate level switch in the sump acts as a hard dry-run interlock, so the pump is protected even if a transmitter cable is damaged.
Common Level Measurement Mistakes to Avoid
- Choosing ultrasonic for a tank with heavy foam or vapour.
- Ordering a hydrostatic cable that is too short for the real well depth.
- Not venting the hydrostatic cable as specified, which causes drift.
- Installing a float-type probe in a liquid that builds up deposits.
- Relying on one sensor with no independent dry-run or overflow switch.
What to Send for a Level Transmitter Quote

Frequently Asked Questions
Which level transmitters do you supply in Ahmedabad?
We supply the RB XSENSE RB21W hydrostatic level transmitter, the RBL01 magnetostrictive level transmitter, ultrasonic level sensors, laser distance sensors and level switches.
What is a hydrostatic level transmitter?
A hydrostatic level transmitter is lowered into a tank or well and measures the pressure of the liquid column above it. Since pressure rises with depth, the reading converts directly into level.
Which level transmitter is best for a bore well or water tank?
A hydrostatic level transmitter is usually the best fit for bore wells, sumps and water tanks because it is simple, robust and not affected by foam or vapour above the water.
When should I use a non-contact level sensor?
Use an ultrasonic or laser sensor when the medium should not be touched, for example aggressive chemicals, or when the sensor cannot be installed inside the tank.
What is the price of a level transmitter in Ahmedabad?
The price depends on the measuring principle, range, cable or probe length, output and quantity, so RB Automation quotes each requirement. Use the form on this page, call +91 8511104864 or email contact@rbautomate.com.
