Badger Hedland Flow Meter: Sourcing High-Pressure Inline Hydraulic Oil Dials
Quick Answer: Silver Automation Instruments supplies and sources Badger Hedland style high-pressure inline hydraulic oil dial flow meters. For a fast quote send your oil type, viscosity, pressure in bar, temperature in °C, port size in DN or inch, and flow range in L/min. Most hydraulic loops need a 350 bar rated meter with direct reading dial and BSPP or SAE ports.
This page is for engineers and buyers who need a high-pressure inline hydraulic oil dial flow meter. We cover the key specs, common regions, lead time, and how to request pricing from Silver Automation Instruments. We ship to Southeast Asia, Oceania, Latin America, Africa, and the Middle East.
What to Check Before You Source a Hydraulic Oil Dial Flow Meter
Pressure rating is the first thing. A power unit or oil skid often runs between 180 and 280 bar. Peak pressure during cold starts can reach 350 bar or more. The meter must handle that peak, not just the working pressure. Some Hedland style inline meters are rated for 350 bar continuous and 450 bar peak on smaller port sizes. Always confirm with the supplier.
Flow range matters more than most buyers think. A hydraulic pump circuit may never drop below 10 L/min. A test bench may need 2 to 30 L/min. If you pick a meter for the maximum flow only, you may lose the low-end signal. Send the minimum, normal, and maximum flow in L/min or GPM. We have seen this issue on customer sites many times.
Oil type and viscosity. ISO VG 32, VG 46 and VG 68 are common. Phosphate esters need different seals. High viscosity oils raise pressure drop. Most dial flow meters work fine with mineral hydraulic oil. For very high viscosity or non-conducting fluids, we may recommend an oval gear flow meter from Silver Automation Instruments.
Port size and thread. Tell us if the connection is BSPP, BSPT, NPT, or SAE. Common sizes are DN10, DN15, DN20, DN25, 1/2 inch NPT, 3/4 inch NPT and SAE 8. A mismatch here causes delays. A hydraulic power unit builder in Vietnam sent us a request last month. He needed a 1/2 inch NPT dial meter for ISO VG 46 oil at 80 °C and 180 bar. We confirmed the flow range and shipped from stock.
Badger Hedland Style Meters We Source
The Badger Hedland flow meter line covers direct reading dials for hydraulic oil, water-based fluids, and phosphate esters. We quote both stock and non-stock part numbers. The H600 and H700 series are common for high-pressure hydraulic oil service. For a 350 bar loop with 5 to 30 L/min and SAE 8 ports, a Badger Hedland H701A style meter is often a fit. For lower flow test stands with 2 to 20 L/min and BSPP 1/2 inch ports, we may suggest an oval gear flow meter because of better low flow performance.
Most engineers skip this part. A direct reading dial needs no power supply. That meter is reliable for hydraulic power units and oil skids where 4-20 mA HART loops are not always available. If you need remote output, we can add a transmitter or switch to the meter. Tell us if you need 4-20 mA, pulse, or a simple alarm trip.
Where These Meters Are Used
We supply these high-pressure
In Southeast Asia, many customers in Vietnam, Indonesia, and the Philippines order these meters for hydraulic oil skids. In Latin America, we see requests from Mexico and Chile for mining equipment hydraulic test stands. In the Middle East, offshore hydraulic power units for oil and gas often need 350 bar rated dial meters with robust internals. We handle these export requests from flow-meter.com.au and from our Shanghai office.

FAQ
Q: Can Silver Automation Instruments supply genuine Badger Hedland flow meters?
Answer: Yes. We source genuine Badger Hedland high-pressure inline hydraulic oil dial meters. Send the full part number if you already have it. If not, send the process data and we will confirm the exact model.
Q: What pressure rating should I choose for a hydraulic oil dial flow meter?
Answer: Choose a meter rated for your peak system pressure, not just the working pressure. For most hydraulic power units, 350 bar continuous is a safe starting point. Confirm the peak pressure with your hydraulic schematic.
Q: What is the difference between a dial flow meter and an oval gear flow meter for hydraulic oil?
Answer: A dial flow meter is a variable area type that gives direct local indication without power. An oval gear flow meter is a positive displacement type with better low flow accuracy on high viscosity oil. We recommend an oval gear meter for small test benches or oils above 100 cP.
Q: Do I need a 4-20 mA output on a hydraulic oil flow meter?
Answer: Only if a PLC or control system must read the flow. Many hydraulic power units use a local dial only. If you need remote output, we can supply a transmitter or switch option.
Q: How fast can you ship to Vietnam, Indonesia, or Mexico?
Answer: Stock sizes in DN15 and DN20 often ship within 5 to 7 working days. Non-stock Badger Hedland part numbers may take 2 to 4 weeks. We confirm lead time with your quote.
