Flow Measuring

Mass Flow Controller (MFC) is a device used to measure and control the flow of liquids and gases. A mass flow controller is designed and calibrated to control a specific type of liquid or gas at a particular range of flow rates. The MFC can be given a set-point from 0 to 100% of its full scale range but is typically operated in the 10 to 90% of full scale where the best accuracy is achieved. The device will then control the rate of flow to the given set-point. MFCs can be either analog or digital. A digital flow controller is usually able to control more than one type of fluid whereas an analog controller is limited to the fluid for which it was calibrated.

All mass flow controllers have an inlet port, an outlet port, a mass flow sensor and a proportional control valve. The MFC is fitted with a closed loop control system which is given an input signal by the operator (or an external circuit/computer) that it compares to the value from the mass flow sensor and adjusts the proportional valve accordingly to achieve the required flow. The flow rate is specified as a percentage of its calibrated full scale flow and is supplied to the MFC as a voltage signal.

Mass flow controllers require the supply gas or liquid to be within a specific pressure range. Low pressure will starve the MFC of fluid and cause it to fail to achieve its set-point. High pressure may cause erratic flow rates.

Our company is supplying some reliable brands of Flow meter and controller such as Brooks, Bronkhorst, MKS and Dwyer for its customers

Pressure Controlling

A pressure regulator is a valve that automatically cuts off the flow of a liquid or gas at a certain pressure. Regulators are used to allow high-pressure fluid supply lines or tanks to be reduced to safe and/or usable pressures for various applications.

Gas pressure regulators are used to regulate gas pressure and are not used for measuring flow rates.

Our company is supplying some reliable brands of Pressure Regulator such as GO, Tescom, Swagelok and Fisher for its customers.

Metering Pumps

A metering pump moves a precise volume of liquid in a specified time period providing an accurate flow rate. Delivery of fluids in precise adjustable flow rates is sometimes called metering. The term “metering pump” is based on the application or use rather than the exact kind of pump used, although a couple types of pumps are far more suitable than most other types of pumps.

Many metering pumps are piston-driven. Piston pumps are positive displacement pumps which can be designed to pump at practically constant flow rates (averaged over time) against a wide range of discharge pressure, including high discharge pressures of thousands of psi.

We are so pride that exclusively provide Optos Electronic Metering Pumps, HP Manual Metering Pumps, VS Variable Speed Metering Pumps.

Vacuum Pumps

Vacuum pump is a device that removes gas molecules from a sealed volume in order to leave behind a partial vacuum. These Pumps can be broadly categorized according to three techniques as Positive displacement pump, momentum transfer pump, Regenerative pump.

In this field we are providing Edward Vacuum products and Woosung Korea.
