Import Diesel Industry Oil Oval Gear Flow Meter — Buy in wholesale FOB from Supplier in China

The Diesel Industry Oil Oval Gear Flow Meter from Shanghai JSN Micro Flowmeter Company is a precision instrument designed for accurate measurement of viscous diesel fuel and lubricating oils in industrial systems. It features twin oval gears made from hardened stainless steel 316L, with a measurement range of 0.2 to 20 L/min and a repeatability of ±0.2%. The housing is cast aluminum with an IP65 rating, and the output is a pulse signal compatible with standard PLC inputs. This unit is calibrated using a gravimetric reference system traceable to NIST standards.

Unlike many mass-produced units from Dongtai’s cluster factories, this meter is assembled using in-house machined components and a Siemens-derived numerical control system. The gear geometry is optimized for low torque and minimal slippage in sticky media, a common failure point in cheaper models. The bearing system uses ceramic ball bearings, not standard steel, to resist wear from particulate contamination. These design choices reflect a focus on long-term stability rather than low initial cost.

This flow meter is primarily purchased by manufacturers of diesel-powered industrial generators, marine fuel systems, and hydraulic lubrication circuits requiring precise dosing. Buyers typically order in batches of 5 to 50 units, with standard packaging in foam-lined wooden crates. Lead time is 15 to 20 working days after order confirmation. Incoterms offered are FOB Shanghai, with payment via T/T or L/C. Calibration certificates are provided per unit upon request.

Shanghai JSN Micro Flowmeter Company was founded in 2008 by Mr. Tu Jianwen, a former senior engineer at Siemens Germany, who relocated from Cixi to Shanghai to address quality gaps in China’s flow meter industry. The company does not assemble imported components; it machines its own gear sets and housing using CNC equipment calibrated to Siemens-derived software. The supplier has no public certifications listed and does not claim ISO status. Its trust tier is harbor, indicating basic verification of legal registration and physical address.

The company does not disclose annual production volume, employee count, or client names. It does not operate a public website or export portal. Communication is handled directly through inquiry systems, with no recorded response history. The supplier’s value proposition rests on engineering heritage, not marketing claims. No claims are made regarding export volume, international clients, or certifications beyond what is implied by the calibration process described in the product description.
