The guide compares oval gear, helical gear and Coriolis meters for heavy fuel oil, lubricants and resins, with viscosity limits and flow derating data.
NANJING, CHINA - Media OutReach Newswire - 27 October 2026 - Silver Automation Instruments Ltd., a Nanjing-based supplier of industrial flow, level and pressure instrumentation, has published a technical guide on how to select a high-viscosity oil flow meter. The guide is written for engineers who meter high visocsoity liquid ,such as heavy fuel oil, lubricants, hydraulic oil, resins and other liquids above 200 mPa·s.
Coriolis flow meter for high viscosity crude oil measurement
Between January 2025 and Sep 2026, the company received 3000 flow meter inquiries from 130 countries. 8% involved oils or liquids above 200 mPa·s, mainly from heavy fuel oil and marine fuel, bitumen, molasses and syrups, mineral slurries, coating slurries and epoxy resins. These cover the oil and gas, marine, road construction, food processing, mining, coatings and chemical industries. Most of them are trading agents and engineering integrators.
Why viscosity changes the choice
Viscosity is the first parameter to check. Many common flow sensor types lose accuracy as it rises. Turbine flowmeters slow down or break down as fluid drag increases. Vortex flowmeters need a minimum Reynolds number that thick oil rarely reaches. Electromagnetic meters cannot measure oil, because oil is not conductive liquid.
Positive displacement flow meters behave the other way. Thicker oil leaks less between the gears and the housing, so slip drops and accuracy holds. The trade-offs are higher pressure loss and a narrower usable flow range.
Coriolis mass flow meters take a third route. The flow sensor measures high viscosity liquid mass flow directly from the twist of vibrating tubes, so viscosity does not change the measuring principle. The same flow sensor also reads density and temperature. There are no moving parts to wear, and no inlet or outlet straight runs are required. Accuracy ranges from ±0.1% to ±0.5% of flow. Thick oil raises the pressure loss across the tubes, so the flow sensor is often sized one step larger than the line. That sizing should be calculated from the actual viscosity, not read from a standard flow table.
Key data from the guide
- Oval gear flow meters handle viscosity up to 2,000 mPa·s at 0.5% or 0.2% accuracy, in sizes 1/8 inch to 8 inches.
- Helical gear flow meters extend the limit to 3,500 cP with low pressure loss, and max size is 14 inches(DN350)
- Coriolis mass flow meters measure mass directly and are not affected by viscosity. Accuracy ranges from ±0.1% to ±0.5%. Sizing must account for the higher pressure drop of thick liquids.
- Flow range shrinks as viscosity rises. A DN50 oval gear meter covers 8 to 24 m³/h on light oil, but only 1.2 to 12 m³/h at 1,000 to 2,000 mPa·s.
- Heated oil needs a high-temperature radiator. With this option, oval gear meters reach 200°C and helical gear meters reach 250°C. A heating jacket keeps oil from setting inside the meter body.
"Most selection errors we see come from sizing by pipe size, not by viscosity at operating temperature," said Ellen Sheng, Sales Engineer of Silver Automation Instruments. "A meter sized for diesel can be too small for the same flow of heavy fuel oil. We wrote this guide so engineers can check that before they send an RFQ."
The guide closes with a five-point checklist: viscosity at the lowest operating temperature, flow range at that viscosity, allowable pressure loss, process temperature, and required output (pulse, 4-20mA, HART or RS485).
The full guide is available on the Silver Automation Instruments website. Engineers can also submit process data for free meter sizing.

SINGAPORE – Media OutReach Newswire – 27 October 2026 – Singapore fashion label Anmako has launched the SEISO Collection, a new range of occasion wear in Singapore designed for weddings, celebrations, formal events and professional settings.
Anmako Launches SEISO, a New Occasion Wear Collection in Singapore
Officially launched on 21 August 2026, the collection takes its name from the Japanese term 「正装」, meaning "formal wear", reflecting its focus on clothing for special occasions.
The collection was developed in response to customer demand for occasion wear, particularly for clothing suited to weddings, anniversaries and other significant events. It also expands the brand's existing range, which covers everyday, holiday and formal wear.
The SEISO Collection incorporates heritage-inspired fabrics and silhouettes into contemporary designs. Traditional elements have been retained and adapted to create pieces intended to remain relevant beyond a single season.
"The SEISO Collection elevates our signature designs and craftsmanship into a more refined collection created especially for formal and meaningful occasions," said Eiko Sumantri, Director of Anmako.
Batik Tulis Features Across the Collection
Batik Tulis is one of the main materials used in the SEISO Collection. Anmako's batik fabric is mainly produced in Pekalongan and Cirebon, with many pieces made in limited quantities or as one-of-a-kind designs.
The collection also includes Batik Tulis Prada, a type of Batik Tulis featuring gold detailing. SEISO is also the brand's first collection to include Natural Dye Batik Tulis.
Produced using plant-based dyes, the natural-dye fabric appears in softer shades such as smoky green and blue. It is used in the Batik Tulis Natural Dye Dress, providing a more understated contrast to the brighter colours found in some of the cotton-and-silk Batik Tulis pieces.
Contemporary Adaptations of Traditional Silhouettes
Several designs in the collection reinterpret traditional garment forms for contemporary use.
The Sarong Skirt takes inspiration from the traditional sarong but uses a back zip instead of a wrap-and-tie construction. This allows the skirt to retain the overall appearance of a sarong while making it easier to wear.
The Batik Tulis Cotton/Silk Cheongsam Dress expands on Anmako's approach to the batik cheongsam by combining a cheongsam silhouette with Batik Tulis fabric. The cotton-and-silk blend gives the material a subtle sheen compared with pure cotton, making it more suited to formal occasions.
The collection also includes the White/Gold Lace Dress, which differs from many of Anmako's existing designs as it uses neither batik nor Japanese fabric. The dress features a clean silhouette with gold detailing, adding another option to the SEISO range.
Most of the occasion wear pieces in the SEISO Collection are one of a kind.
Designed for a Range of Formal Occasions
Anmako developed SEISO for customers looking for occasion wear for weddings, graduation ceremonies, conferences, important meetings, festive celebrations and other significant occasions.
The designs have also been kept relatively timeless so that they can be worn beyond a single event or season. Through the collection, Anmako continues to incorporate traditional textiles and garment influences into clothing made for contemporary use.
"We developed SEISO in response to customers looking for distinctive occasion wear pieces for weddings, anniversaries and other special occasions," said Eiko. "It gave us an opportunity to bring the fabrics and craftsmanship associated with Anmako into a collection created specifically for these moments."
The SEISO Collection is available at Anmako's store on Level 3 of Takashimaya and through the Anmako online store, with prices ranging from S$229 to S$899.
The collection will remain available throughout the rest of 2026 and through the Chinese New Year period in 2027.Hashtag: #Anmako
