Why Accumax
Why Accumax
Specifications published, not withheld
Every datasheet is on this site, free and without a form. You should be able to decide whether an instrument fits before you talk to anyone.
In-house R&D and calibration
Meters are wet-calibrated in an IEC/ISO/EN 17025 accredited laboratory before they ship.
Built for the fluid, not the catalogue
Liner, electrode and body materials are selected per application. A meter for slurry is not a meter for treated water.
Since 1992
Three decades of process control instrumentation, from telecom electronics to flow measurement and industrial IoT.
Our Mission
Grow steadily over the years integrating diverse technologies to solve complex measurement problems and needs.
Our Vision
Combining technological advances with stringent safety standards, corporate social responsibilities, and green values.
Strategy
Offering nearly all of the commercially available measurement and process technologies, and a wide range of custom applications.
Goal
Customer-focused and solution-driven partnership with customers and OEMs, to convert ideas into reality.
Resources
Datasheets, brochures and manuals
26 datasheets, brochures and manuals across the range. No sign-up, no form — the specifications should be readable before you talk to us.

Frequently asked questions
Can’t find your answer? Our engineers reply on WhatsApp at +91 88496 70588.
Which instruments does Accumax manufacture?
Our range includes electromagnetic, ultrasonic, turbine and paddle wheel flow meters; flow and batch controllers; piezometers and digital water level recorders; ultrasonic level transmitters; pH analysers; and industrial IoT devices. Product pages provide application details, specifications and available outputs.
How do I choose a flow meter for my application?
Share the fluid, pipe size, minimum and maximum flow, operating temperature and pressure, required accuracy, and any approvals. Electromagnetic meters measure conductive liquids; other technologies suit different duties. Our engineers can check material compatibility and recommend a configuration for your process.
How are Accumax electromagnetic flow meters calibrated?
The electromagnetic flow meter datasheet specifies wet calibration at an IEC/ISO/EN 17025 accredited calibration laboratory. When requesting a quotation, confirm the calibration documentation, measurement range and accuracy required for your installation.
Can instruments connect to SCADA or remote monitoring systems?
Depending on the instrument and configuration, outputs include 4–20 mA, pulse and RS485 Modbus. Telemetry-enabled meters, data loggers and IoT devices support remote monitoring. Check the individual datasheet and confirm the required interface and telemetry options before ordering.
How can I request a quotation or place an order?
Use Get a Quote, WhatsApp +91 88496 70588, or email accumaxinstruments@gmail.com with the product name, quantity, process requirements and company details. Our team will confirm the suitable configuration, price and delivery schedule before you place an order.
