Diesel Oil Flow Meter DN150 for Distribution Terminals

Quick Answer: Need a reliable meter for loading diesel at a 6-inch (DN150) distribution terminal? Silver Instruments recommends the oval gear flow meter with 0.5% accuracy, 4-20 mA HART output, and a flow range up to 1000 m3/h. It handles diesel viscosity from 2 cP to 200 cP, works at 40 bar pressure, and comes with ATEX Zone 1 certification for tank truck loading bays.

Why Oval Gear Meters Dominate Diesel Custody Transfer at Terminals

When a distribution terminal in the Middle East approached us last year, they needed a DN150 meter for diesel loaded onto road tankers. The back pressure was 8 bar, temperature 35 °C, and flow rate up to 800 m3/h. They had tried turbine meters before but found them drifting after three months due to wax buildup in diesel. Here is the thing: positive displacement meters like oval gear meters simply lock onto the fluid volume and ignore viscosity swings. That is crucial for diesel because it changes from 3 cP on a cold morning to 10 cP in storage. A mass meter like Coriolis would work but the cost for DN150 was six times higher. So the terminal chose four units of our oval gear flow meter DN150 with tri-clamp connections and a pulse output feeding into their top-up PLC. No bypass line needed.

DN150 Mechanical and Electrical Specs You Should Know

The oval gear meter for DN150 pipe handles diesel at line sizes from 6 inch schedule 40 or DN150 PN16 flanges. Flow range: 60 to 1000 m3/h. Turndown 1:16. Pressure rating: PN40 or Class 300, with cast steel or stainless steel body. Temperature: -20 °C to 120 °C. Viscosity limit: 2 to 200 cP for diesel, up to 1000 cP for heavy fuel. Output signals: pulse, 4-20 mA HART, or RS485 Modbus. Accuracy stays at 0.5% of rate or better across the range. We often factory calibrate with diesel at 40 °C to match real terminal conditions. If you need explosion proof, specify ATEX Zone 1 or IECEx for your motorized valves and loading arms. In practice, most distribution terminals only need a local display with pulse output to a batch controller. We have seen this on customer sites many times: they skip the HART wiring and just use a magnetic pickup because it is cheaper and still certified for custody transfer under OIML R117.

Four Distribution Terminal Demands That Drive Meter Selection

Distribution terminal managers focus on four things: zero leakage, fast loading, repeatability, and low maintenance. Oval gear meters have no bypass, so zero leakage is built in. The DN150 unit can fill a 30,000 liter tanker in under three minutes at 600 m3/h

with back pressure under 3 bar. Repeatability is 0.05%, so the metering skid passes legal metrology checks each year without re-calibration. Because the gears run on diesel lubrication, a set of stainless steel gears in a cast iron housing lasts five to seven years in a heavy duty rack with one shift per week of cleaning. A terminal in Indonesia uses six of our DN150 meters for palm oil biodiesel blends (B30) and only changes the PTFE seals every 18 months. That is a real number we track for warranty claims. So if your terminal blends biodiesel into diesel, ask for FKM or PTFE seals and a stainless body to avoid corrosion from methanol traces.

How to Order a DN150 Diesel Flow Meter from Silver Instruments

We ship to terminals in Vietnam, Saudi Arabia, Brazil, Nigeria, and Australia within two weeks. Send us these four numbers by email: diesel flow rate in m3/h or liters per minute, pipe diameter (DN150 or 6 inch), operating pressure in bar, and fluid temperature in °C. We will send a quotation with the oval gear meter, a pulse transmitter, calibration certificate, and a 2-year warranty. Most terminals add a strainer with 100 micron mesh upstream, we often include it on the same base plate. For remote monitoring, add a paperless recorder or RTU with GSM modem. You can see our oval gear flow meter datasheet on flow-meter.com.au. Use the contact form or email info at flow-meter.com.au, add your phone number and we will call you back on WhatsApp in one business day.

FAQs on DN150 Diesel Flow Meter for Distribution Terminals

Q: Can the DN150 meter handle biodiesel blends up to B30? A: Yes. We recommend stainless steel gears and FKM seals for biodiesel with methanol content below 5%. We have installed 22 units in a Jakarta terminal running B30 24/7 since 2021 without gear wear.

Q: What is the typical delivery time for a DN150 oval gear meter? A: Ex stock for flange and pulse output version takes 5 working days. Customized ATEX packages need 3 weeks.

Q: Does the meter come with a flow computer for custody transfer? A: You can pair it with an external batch controller like the SI-701. We also supply complete skids with a strainer, air eliminator, and control valve.

Q: What is the price range? A: A DN150 oval gear meter with standard cast iron body starts at 8,500 USD FOB Shanghai. Accuracy 0.5% and pulse output included.

Q: Can I get a remote reading via Modbus? A: Yes, we integrate an RS485 Modbus module inside the transmitter housing. You get real time flow rate, total, and diagnostics on your SCADA.
