What Mechanical Engineers does
Mechanical Engineers is a privately held, Kolkata-based industrial manufacturer (also doing business as Mechflow) founded in 1993 by Mr. J.K. Sarkar. The company designs and manufactures primary flow elements — Venturi Tubes, Orifice Plates, Flow Nozzles, Krellbars, and Wedge Flow Meters — used for differential-pressure flow measurement in pipelines and ducts. All products are designed in accordance with the international standards BS-1042 and ISO-5167, and the operation holds ISO 9001:2015 certification. The company also maintains a proprietary orifice plate calculation software that incorporates discharge coefficients, expansibility factors, Reynolds numbers, thermal expansion correction, and other fluid properties to size orifice plates for specific applications.
The customer base is entirely B2B and comprises two channels: direct supply to major Indian industrial end users (TATA Steel, JSW, JSPL, THERMAX, L&T, VOLTAS, NTPC, ONGC, Indian Oil, BHEL, and others) and OEM supply of flow elements as package components to global instrument manufacturers (ABB, Honeywell, Yokogawa, Emerson, Endress+Hauser, Blue Star). Revenue is generated exclusively through custom-engineered, quotation-based hardware sales with no subscription or recurring component, conducted via direct phone, email, and a website inquiry form that captures detailed process specifications. Marketing is minimal and limited to a static website; the company has no disclosed social media presence, app, or API offering.

Mechanical Engineers product offering
Product offeringCore offering
Mechanical Engineers manufactures primary flow elements including Venturi Tubes, Orifice Plates, Flow Nozzles, Krellbar flow meters, and Wedge Flow Meters. These are differential pressure-based flow measurement devices used in industrial process plants for accurate measurement of fluid flow rates in steel, power, oil & gas, and chemical facilities.
Product overview
Mechanical Engineers is a manufacturer of primary flow elements (differential pressure flow measurement devices) for pipelines and ducts. The product portfolio comprises five distinct flow element types: Venturi Tube (low-pressure-drop metering device with tapered inlet and pressure recovery), Orifice Plate (most commonly used primary element with various tapping configurations), Krellbar (designed for large cross-sectional ducts and dusty gaseous fluids), Flow Nozzle (for high-velocity applications including high-pressure steam), and Wedge Flow Meter (suitable for low Reynolds numbers and viscous/slurry media). All products operate on the differential pressure principle and are designed per BS-1042 and ISO-5167 international standards. The company was founded in 1993 and supplies to major industrial clients including steel plants, power plants, oil and gas facilities, and process industries.

Mechanical Engineers competitors and assessment
Company assessmentDirect peers
- Spirax Sarco: UK-headquartered specialist in steam and industrial fluid measurement, including primary flow elements and associated control equipment. Comparable niche specialization in steam/process flow measurement with similar primary element products.
- KROHNE: German-headquartered global specialist in industrial process measurement, including primary flow elements (Venturi tubes, orifice plates, flow nozzles) and complete flow meters. Closest global analog as a focused flow measurement primary element manufacturer.
- Forbes Marshall: Indian-headquartered specialist in steam engineering and flow measurement, including primary flow elements and control instrumentation. Directly comparable niche, same regional customer base, and already a customer reference on Mechanical Engineers' site.
- Badger Meter: US-based specialist in flow measurement technologies and primary elements for water, industrial and commercial applications. Comparable product focus on primary flow elements, though serving primarily Western markets.
- McCrometer: US-based flow measurement specialist focused on differential pressure and proprietary primary element designs for industrial water, oil & gas applications. Comparable mid-sized specialist profile with concentrated flow measurement product line.
Broad incumbents
- Emerson (Rosemount): US-based global automation major with extensive flow measurement portfolio under Rosemount brand, including DP primary elements and integrated transmitters. Customer of Mechanical Engineers for OEM supply and a global benchmark competitor.
- Endress+Hauser: Swiss global leader in industrial process measurement instruments across flow, level, pressure, temperature and analytics. Overlapping primary element portfolio at much broader scale; also listed as a customer of Mechanical Engineers for OEM packages.
- ABB Measurement & Analytics: Global automation major with a strong flow measurement portfolio spanning primary elements, transmitters and complete skid packages. Both a customer of Mechanical Engineers (for OEM packages) and a broad-incumbent competitor in the same accounts.
