Set the target flow
Enter the target flow on the touchscreen; the controller takes it as the speed reference for the drive.
An integrated fluid delivery platform for low-speed, micro-flow duty. Step / servo motor speed control and a bilingual touchscreen turn flow adjustment on a micro gear pump into something simple and deterministic.
Dosing precision
Response time
Turndown ratio
The JONSN micro gear pump flow control system is an integrated fluid delivery platform built for laboratory pilot and bench-scale stages. A filter, high-precision gear pump, servo motor, high-precision flow meter, pressure sensor and valves are all pre-installed inside one desktop cabinet.
Through closed-loop linkage between the flow meter signal and the gear pump servo motor, the system automatically matches set flow to actual flow, and displays online instantaneous flow and pressure fluctuation in real time. Flow control moves from repeated manual valve adjustment to set-and-go. In daily use you only connect the inlet and outlet lines, complete the flow meter parameter setup on the touchscreen, and start — no complex commissioning required.



Built for conditions where system pressure differential is unstable but flow precision requirements are high. Pressure fluctuation is compensated automatically by the loop, so the flow output stays constant.
Enter the target flow on the touchscreen; the controller takes it as the speed reference for the drive.
The Coriolis mass flow meter measures actual flow continuously and returns the signal to the controller.
The controller computes the deviation between set flow and measured flow, in real time.
Servo motor speed is corrected until the deviation falls back inside the tolerance band.
Suitable for operating conditions with unstable system differential pressure but high flow-rate accuracy requirements — pressure fluctuations are automatically compensated through closed-loop control, maintaining a constant flow output.
High-precision delivery
Dosing precision reaches ±0.5‰, meeting metering-class requirements for micro flow.
Fast response
Response time is only 50–200 ms, so the output follows a process change immediately.
Wide turndown
A turndown ratio of 1:100 means one unit covers multiple process setpoints.
The delivery element of the system, metering micro flow at ±0.5‰ precision.

Online monitoring of pressure fluctuation, so back pressure stays inside the control band.

The closed-loop feedback signal source, measuring mass flow directly.

Bilingual Chinese / English interface for parameter setting, display and alarm.

Stabilises back pressure and suppresses pulsation at the delivery line.

Integrated as standard
A filter and valves are integrated into the system, so you do not need to select or source supporting components separately.
The unit is assembled and commissioned before it leaves the factory. You only connect the inlet and outlet lines and power it on.
Place the cabinet on the bench and connect inlet / outlet lines
Power on, set flow meter parameters on the touchscreen
Enter the target flow and start — no on-site tuning
Micro flow delivery for processes where the setpoint must hold while pressure moves:
Fine chemicals
Pharmaceutical
Automation equipment
Semiconductor processing
Fuel cell
