What flow meter can be used for oil low flow rate?

Gear flow meter is a kind of inline digital low flow oil flow meter. The oil min flow it can measure is 0.6-50 Liter/h (0.01-0.833 L/min), it is very ultra low flow oil flow meter. Gear flow meter is positive displacement flow meter; it can be made into low velocity oil flow meter. Positive displacement flow meters are flow sensors that directly accumulate oil flow based on the volume of discharged oil; we also call it PD flow meters. It uses a mechanical measuring element to continuously divide the oil into a single known volume part, and measures the total volume of the oil flow according to the number of times that the measuring chamber is filled with and discharged the volume part of the oil successively.

What kind low flow oil can be measured?

Gear flow meter can handle different kinds of oil, no matter low viscosity oil or high viscosity oil. The max viscosity gear flow sensor can handle is 10000 cp.

Oil types can be measured by gear flow meter for micro flow rate:

Edible oil, scutellaria oil, sesame oil, rapeseed oil, soybean oil, melon seed oil, corn oil, peanut oil, fat, animal edible oils include lard, mutton, and tallow, fish oil, industrial oils, mainly hydraulic oil, petrol oil, gear oil, turbine oil, compressor oil, refrigerating oil, transformer oil, vacuum pump oil, bearing oil, fuel oil, metal processing oil, grease, cylinder oil, heat treatment oil and heat transfer oil.
