Custody Flow Meter Sourcing for Pipeline Distribution and Custody Transfer
Quick Answer: For custody transfer in pipeline distribution, select a Coriolis mass flow meter for refined products and small to medium lines, or an inline ultrasonic flow meter for large water and crude oil mains. Send your pipe size (DN), flow range, pressure, temperature and fluid type to Silver Automation Instruments. We will return a specific model, calibration scope and quotation.
Custody flow meter sourcing is different from standard process meter buying. The meter becomes part of a commercial transaction. A small repeatability error can create a large financial difference over a month of pipeline distribution. We have seen this in diesel terminals, crude oil custody points and industrial gas pipelines across Southeast Asia, the Middle East and Latin America.
This guide covers custody flow meter sourcing for pipeline distribution and custody sourcing portals. It is written for engineers and procurement teams who need a meter that can be trusted in a fiscal or commercial metering point.
What a Custody Flow Meter Must Do
A custody flow meter has to measure the amount of fluid that changes ownership. It must hold calibration over long periods. It must match the local metrology rules and the contract between buyer and seller. For refined diesel distribution, a DN80 Coriolis meter with 0.1 percent mass accuracy is a common starting point. For a 20 inch crude oil main, a multi path ultrasonic meter often fits better because of line size and pressure drop limits.
Our CFM series Coriolis mass flow meter covers DN3 to DN200. It handles flow from 0.1 kg/h to 1 000 000 kg/h. It supports 4-20 mA HART, Modbus and pulse output. We also supply inline and clamp-on ultrasonic meters for DN25 to DN3000 lines. This range lets us cover small additive injection lines and large water distribution mains.
Custody Sourcing Portals Are a Starting Point Only
Procurement teams in Vietnam, Thailand and Indonesia often begin on regional custody sourcing portals. They search for custody flow meter manufacturer or custody transfer flow meter price. Here is the thing. A portal listing often hides the calibration range, wetted material and local approval status. That missing data can change the price by 40 percent or more.
In practice, a direct manufacturer quote works faster when the buyer supplies complete process data. Last month a fuel distributor in Lagos asked for a custody meter through a sourcing portal. The initial offer was for a turbine meter. After we received the actual viscosity and flow turndown data, the correct choice changed to a DN50 Coriolis meter. The customer avoided a low flow accuracy problem before purchase.
Technical Data to Prepare Before You Request a Quote
You do not need a full data sheet to start. But you should know six items. Fluid type, line size, flow range, pressure, temperature and hazardous area class. For example, a chemical plant in Saud
If the fluid is demineralized water with conductivity below 20 µS/cm, an electromagnetic meter will not work well. Choose a Coriolis meter or an ultrasonic meter instead. If the fluid is heavy fuel oil at 380 cSt, a turbine meter may fail on cold startup. For palm oil at 45 cP and 80 °C in Malaysia, a Coriolis meter gave stable batch totals without a separate density meter. These small details change the sourcing decision.
Regional Installation Notes for Pipeline Distribution
A water utility in Ghana needed a battery powered flow meter for a 300 mm pipeline because no 24 V DC supply existed at the meter pit. We supplied a battery powered inline ultrasonic meter with Modbus output and a local data logger. The custody data moved to their sourcing portal through a cellular modem. In Oman, a crude oil operator required ATEX Zone 1 certification and stainless steel wetted parts. The meters shipped with third party calibration certificates and sealed transmitters.
FAQ
What is the best custody flow meter for diesel pipeline distribution?
A Coriolis mass flow meter is usually the best first choice for diesel distribution. It measures mass directly and handles viscosity changes. For large diesel mains above DN250, an ultrasonic meter may reduce pressure drop and total cost.
Can Silver Instruments supply custody transfer flow meters with calibration certificates?
Yes. We provide factory calibration and third party certificates when the contract requires them. Tell us the custody standard and the local metrology approval body before ordering.
What information is needed for a custody flow meter quote?
Send fluid type, pipe size (DN), minimum and maximum flow rate, operating pressure, operating temperature, output signal and hazardous area class. Also tell us the country of installation. We will match the meter to local approvals.
Do you support ATEX Zone 1 and hazardous area custody metering?
Yes. We supply custody flow meters for ATEX Zone 1 and Zone 2 installations. Ex d, Ex ia and flameproof versions are available depending on the transmitter and sensor combination.
How do we source custody flow meters through a local distributor?
Send your project details to Silver Automation Instruments. We will recommend a local distributor or handle the shipment directly if you prefer. You can also visit flow-meter.com.au for product data.
