Low-Flow Flow meter

When talking about small lines and low flow rates gas and liquid flow measurement, ,ultra low flow meter,we have some reliable recommendations, such as small Coriolis flow meter, mini thermal mass flow meters, ultra low flow liquid turbine flow meter, metal tube Rotameter. See below general introductions for the rugged ultra low flow meters also at low price cost.

Coriolis flow meter for ultra low flow fluids measurement-liquid, gas and steam measurement

A small Coriolis flow meter for ultra-low flow applications is a precision instrument designed to accurately measure the mass flow rate of liquids or gases with very low flow rates, the min flow it can detect is 40 g/h, it can measure very low mass flow of pure water, silicone, Silicon-based liquid, aviation kerosene.
The Coriolis flow meter operates based on the principle of Coriolis Effect, which causes a vibrating tube to twist as fluid flows through it. The degree of tube twisting is directly proportional to the mass flow rate, allowing for highly accurate measurements.

In ultra-low flow applications, where the flow rates are typically in the range of a few grams per hour to a few kilograms per hour, conventional flow meters may not provide accurate readings. Therefore, small Coriolis flow meters are specifically designed to address this issue and offer precise flow rate measurements for such low flow rates.
Small Coriolis flow meters are compact in size, lightweight, and built with high-quality materials to ensure minimal interference with the flow of the fluid and reduce the risk of any external factors affecting the accuracy of measurements.

Micro type Ultra Low flow Thermal Mass Flow meter-Gas &air flow measurement at 2-ml/min flow meter

Low flow gas flow meter employs the thermal dispersion principle whereby the rate of heat absorbed by a gas or air flowing in a closed pipe or duct is directly proportional to its mass flow passing. It is a kind of low flow mass flow meter for gas or air.
Thermal flow meters are frequently used for the regulation of low gas flows or air flow; it is a kind of gas flow controller and low flow ml/min flow meter. It can measure CO2, N2, air, He, O2,biogas at low flow rate to 2 cc/min (2 mL/min).

Micro oval gear flow meter  -High viscosity and low flow rate measurement,microfluidic flow meter

LC-M Series Micro oval Gear flow meter can detect ultra mini liquid flow as low as 0.5 ml/min or cc /minute,  (ml/min flow meter), but can still keep accuracy as high as 0.5%F.S, It is a kind of positive displacement flow meter for precise flow measurement of mini or low flow liquid, the liquid include fuel, oil, water,chemical, sealant, toluene, glue, detergents, grease, electrolyte, ethylene, additive, syrup, acryiat-composite.,etc . It is widely used in hydraulic system, lubricating industry and painting industries for fluids low-flow rate measurement., Perfect choice low flow meter for oil.

Low flow magnetic flow meters -Strong corrosive liquid flow measurement

Low flow mag meters can handle liquid flow as low as to 330 ml/min (min flow rate 0.09GPM), the mini eletromagnetic flow sensor size we can provide is 1/8”,1/4”,3/8”,1/2”,3/4”. Micro flow magnetic flow meters are used widely in chemical or fertilizer injection can measure strong aggressive and corrosive liquid, such as HCL, H₂SO₄,  caustic soda,  Phosphoric acid, hydrofluoric acid (HF acid),nitric acid.,etc, however it can also measure water, it is a kind of micro water flow meter.

Metal Tube Rotameter for small flow measurement-Gas ,liquid measurement

Metal tube rot meter is a kind of variable area (VA) flow meter; Rotarmeter is with a tapered tube, a float and scaled indicator, measured medium flow raises a float in the tapered metal tube, adding the area for passage of the fluid, rotameter is a kind of traditional flow meter to handle fluids low flow rate.

Low Flow Liquid Turbine Flow meter-clean liquid measurement

Low flow liquid turbine flow meter is only dedicated to measure clean and not corrosive liquids, cannot measure gas. Miniature turbine flow meter is suitable to measure water or oil with minimum 0.04-0.25 m3/h.

Here we introduce normal type low flow flow meter.
