What Toshniwal Instruments (Madras) Pvt. Ltd does

Toshniwal Instruments (Madras) Pvt. Ltd is an Indian manufacturer, importer, and exporter of industrial process instrumentation founded in 1948 and headquartered in Chennai, Tamil Nadu. The company operates four product lines: process instrumentation (oval gear, electromagnetic, turbine, vortex, Coriolis, thermal mass, and ultrasonic flow meters, plus density meters, level indicators, additive injection blocks, and cryogenic valves), powder processing equipment (single-shaft and twin-shaft paddle mixers and paddle shaft mixer-dryers), temperature measurement products (infrared sensors, pyrometers, and signal conditioners), and — until 2025 — process vacuum systems, the latter having been divested to Ingersoll Rand. Underlying technology is rooted in well-established physical principles (Faraday's law of induction, Coriolis force, Karman vortex shedding, oscillating element density measurement, infrared thermography) executed with proprietary mechanical designs; for example, the twin-shaft paddle mixers achieve homogeneous blends in 30-180 seconds, and Coriolis mass flow meters deliver ±0.15% accuracy across a 0.004-25,000 kg/min range.

The company earns revenue through three streams: direct hardware sales of own-manufactured flow meters, mixers, and process skids; accredited calibration and after-sales services from an NABL-certified facility; and authorized distribution of international principals including Bronkhorst, Fluidwell, Bopp & Reuther, Optris, Sage Metering, PR Electronics, Calex Electronics, and WEKA AG in the Indian subcontinent. GTM is sales-led, executed through enquiry-based direct sales backed by experienced field engineers, supplemented by downloadable product catalogues, a multilingual website, and an inbound blog. Customers span pharmaceutical, chemical, petrochemical, dairy, oil & gas, power generation, automotive, food, textile, refractory, and research organizations, with marquee references including ISRO, BASF, Honeywell, GE, Teva, and HP. The company operates three affiliated entities (Toshniwal Hyvac, Toshniwal Engineering & Systems, Toshniwal Infratech LLP) under common ownership and is privately held, with no external investors disclosed.
