Oil Flow Meter for Sale: Finding In‌-Stock Standard Size Hardware for Quick Shipping

Quick Answer: If you need an oil flow meter in standard sizes like DN15, DN20, or DN25 with pulse or 4‌-20 mA output, Silver Automation Instruments keeps these in stock. We ship same day from our warehouse to Australia, Southeast Asia, the Middle East, and Africa. Send us your pipe size, oil type, and flow range and we will confirm availability in one hour.


Standard size oil flow meters bypass long factory lead times. We hold oval gear meters from DN10 to DN50 on the shelf with BSP or NPT threads. These units measure diesel, lubricating oil, hydraulic oil, fuel oil, and edible oils. The most requested models are DN20 and DN25 because they match common pump discharge lines in small to medium blending and transfer skids. Pulse output with NPN or PNP signal is the default. Most engineers skip specials and take the stock option to avoid paying for custom calibration curves.


Here is the thing. A paint manufacturer in Malaysia asked us for a DN25 oval gear flow meter to dose solvent‌-based additives. They sent us the viscosity data (350 cP at 25 °C), pipe size, and required accuracy of plus minus 0.5 percent of reading. We had the meter in Singapore free‌-trade zone stock with a cast iron body, FKM seals, and a local ATEX Zone 2 declaration. It shipped the same day via DHL. The customer installed it on a Monday. Similar requests come from lubricant blenders in Thailand, diesel generator packagers in Nigeria, and food oil processors in Ecuador. In practice, about seventy percent of our oil meter stock goes to customers who need a direct replacement for a failed mechanical meter or a new skid that failed its pre‌-delivery inspection due to missing flow data.


Our stock meters cover a flow range from 0.6 L/min to 200 L/min depending on DN. Standard accuracy is plus minus 0.5 percent of reading for viscosity above 10 cP. For heavier fuel oils up to 2000 cP, we keep special oval gear meters with larger clearances and cast iron or stainless steel bodies. Because these are also stock items with PTFE gears, there is no custom engineering surcharge. Every meter comes with a factory calibration certificate traceable to national standards. Output options include pulse, 4‌-20 mA, and 4‌-20 mA with HART. For applications that require mass flow instead of volume flow (for example, bunker fuel with density variation), we can configure a Coriolis mass flow meter in two weeks. But if volume totalization is enough, the oval gear meter is the fastest route to a packing slip.


Here is how to secure a unit today. Send us your oil type, viscosity in cP, normal and maximum flow rate (L/min or m³/h), pipe diameter, required signal output, and any hazardous area classification. We will cross‌-check our Nanjing and regional stock and reply with a part number, data sheet, and shipping quote. For urgent requests, message us on WhatsApp at +86‌-25‌-52155837.

What oil flow meter sizes are in stock for immediate shipping?

We keep oval gear meters in DN10, DN15, DN20, DN25, DN40, and DN50 as standard hardware. Thread types are NPT and BSP. Typical materials are cast iron or 304 stainless steel with FKM or PTFE seals. Meters with pulse output and 4‌-20 mA are both in stock. For sizes above DN50, we can confirm availability within two working days but most industrial users find DN25 or DN40 covers their oil transfer and dosing loops.


Can I get an oil flow meter for high‌-viscosity fluids like heavy fuel oil?

Yes. Our oval gear meters handle up to 2000 cP without extra customization. For heavy fuel oil at 80 °C, we supply meters with cast iron bodies, PTFE gears, and a heating jacket option. You specify the operating temperature and viscosity. We then select the internal clearances to keep the pressure drop low and the measurement stable. These are all standard stock configurations because we see this application frequently in Middle Eastern and African power plants.


What accuracy should I expect from a standard oil flow meter?

A standard oval gear flow meter from Silver Instruments delivers plus minus 0.5 percent of reading for oil viscosity above 10 cP. For low‌-viscosity fluids below 5 cP (such as certain solvents), the accuracy drops to plus minus 1.0 percent of reading. Each meter ships with a calibration report showing the K‌-factor across the flow range. We calibrate using mineral oil of known viscosity at our Nanjing facility.


Do you supply oil flow meters with ATEX or IECEx certification?

We have ATEX Zone 1 and Zone 2 certified oval gear meters available on request. Many stock units carry a component certificate or manufacturer declaration that satisfies local inspector requirements in Southeast Asia and the Middle East. If full ATEX/IECEx certification is mandatory for your site, tell us when you send the spec. We will quote the certified variant and confirm lead time (usually two weeks for DN15 to DN50).


How fast can you ship an in‌-stock oil flow meter to my country?

In‌-stock standard meters ship within 24 hours of receiving your order and payment. DHL and FedEx delivery to Australia, New Zealand, Singapore, Malaysia, Indonesia, Vietnam, UAE, Saudi Arabia, South Africa, and Nigeria takes three to seven business days. For larger orders we also offer sea freight consolidations. Provide your delivery address and we will return a door‌-to‌-door courier estimate together with the quotation.
