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.

Small Coriolis Mass Flow Meter Flow Controller

The Small Coriolis Mass Flow Meter Flow Controller by Silver Instruments is designed to provide accurate, real-time flow measurement and control for a wide range of industrial applications.

The low flow it can detect min to 1 g/h, 10 g/h. 40 gram per hour.

For example it can be used for low flow measurement of water, pure water, silicon, supercritical CO2 and so on.

This compact device utilizes the advanced Coriolis principle, ensuring high-precision measurement of mass flow, density, and temperature of liquids and gases.

It offers high accuracy, stability, and reliability even in challenging environments, making it ideal for chemical, pharmaceutical, food and beverage, oil and gas, and energy industries. The flow controller is equipped with customizable settings for flow regulation and integration into automated systems, optimizing process control and minimizing operational costs. Featuring compact size, easy installation, and user-friendly interfaces, it is designed for applications with limited space and stringent flow control requirements. Its advanced digital signal processing provides real-time feedback, ensuring precise flow rate adjustments. This flow controller can effectively handle diverse fluids, including viscous liquids, corrosive substances, and gases. Silver Instruments' flow meters and controllers ensure high performance and are cost-effective solutions for achieving accurate mass flow measurement and reliable flow regulation.

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).
Here is a video to show how our low flow meter works

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.

Here is a video how our micro oval gear flow meters work on low flow measurement.

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 industries.it 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.
