The low pressure proportional pressure regulator can be categorised into
1. low flow
2. high flow
3. economic type

The low flow rate version is ideal for regulating air pressure in a small closed volume, applications include mini cylinder and microfluidics.

The high flow rate version is suitable for dynamic process condition or regulating pressure in a bigger volume container.

The economic type has accuracy of 0.5% F.S, it is also suitable for dynamic process, it is suitable for low pressure control in laser cutting machine.

Series QKL-B1S high pressure low flow electro-pneumatic pressure regulator allows pressure control up to 30 bar ( 435 psi), maximum inlet pressure at 34 bar ( 493 psi). Works in both static or dynamic flow condition without pressure droop.

Resolution can reach up to 5mV. Takes 0-10V, 4-20mA or RS485 signal. Series QKL-B3H I/P transducer provides high pressure high flow version, with flow rate up to 6000 L/min (212 scfm). It is able to reach low pressure in quick response time. Provides feedback signal to monitor pressure output. It is possible to customise pressure range, consult factory for customization.

Kaolu's 70 bar (1015 psi) electronic air pressure regulator provides precision electronic control of pneumatic pressure from 0 to 70 bar. With flow rate up to 170 L/min, it can be used in both static and dynamic conditions.

This series of I/P transducer can reach accuracy up to 0.25% F.S. Takes 0-10V or 4-20mA signal, and provides feedback signal of 0-10V or 4-20mA. It is possible to customise maximum pressure range, consult factory for customization. It is often used to replace GX series pressure control valve.

KMF1000 series digital gas mass flow meter is made of micro- electromechanical system (MEMS) flow sensing chip, suitable for a variety of purposes of clean, relatively dry nature of the small flow gas measurement and process control, unique packaging technology makes the product to meet the different ranges of flow measurement, to ensure high sensitivity, high reliability, high stability and low cost.
