Digital Liquid Batch Controller with Flow Sensor and Solenoid Valve
We supply this digital flow measurement and batch-control kit with a selectable flow sensor, matching normally closed solenoid valve and mains power adaptor. Set the required liquid quantity on the controller to control a measured fill.
Select a flow meter option before ordering. You recieve the sensor and valve combination for that option. UK purchases include a free British mains adaptor.
Choose the sensor and valve size
| Connection size | Sensor and valve material | Listed flow range |
|---|---|---|
| G1/2" | Brass | 1.5–30 L/min |
| G1/2" | Stainless steel | 1.5–30 L/min |
| G3/4" / DN20 | Stainless steel | Confirm before ordering |
| G1" | Brass | 10–100 L/min |
| G1" / DN25 | Stainless steel | 10–100 L/min |
| G1 1/2" / DN40 | Stainless steel | Confirm before ordering |
| G2" / DN50 | Stainless steel | 60–1,000 L/min |
Choose the sensor for the expected flow rate as well as the pipe connection size. A larger connection does not automatically provide better measurement at a low flow rate.
Kit contents
- Digital controller with the selected flow sensor.
- Matching brass or stainless steel normally closed solenoid valve.
- 240 V AC to 24 V DC power adaptor.
- Calibration instructions.
The valve has female inlet and outlet connections in the selected size. We do not sell the sensor, valve or other kit components seperately.
Calibration before use
The meter must be recalibrated on receipt. We provide instructions for adjusting the displayed quantity against a known measured volume.
Carry out calibration in the instaled arrangement using the liquid and flow conditions intended for the job. Check several completed fills before relying on the programmed quantity. Changing the liquid or operating conditions may require another calibration check.
The adjustable readout allows measurement to be corrected for the installation. It does not establish a guaranteed accuracy percentage for every liquid and flow rate.
Liquid applications
The kit can be used for measured water filling into tanks and other containers. Other proposed applications include adding rapeseed oil to an animal feed mixer or measuring liquids in a chilling or dispensing process.
Check material compatibility before using a liquid other than water. Potential applications include wine, milk, beer, diesel, kerosene and oils where the selected sensor, valve seals and operating conditions are suitable. Viscosity can affect flow and measurement so calibration with water alone does not confirm performance with oil.
Food and drink use
A stainless steel body alone dont establish that the complete kit is suitable for food contact. Confirm the stainless steel grade and the suitability of every wetted component including the sensor internals and valve seals.
For milk, wine, beer or other food products also check that the assembly can be cleaned adequately and is compatible with the cleaning products used. Obtain the required food-contact information before selecting the kit for these applications.
Listed operating specifications
- Pressure: up to 1.75 MPa / 17.5 bar.
- Temperature range: −5 to +80 °C.
- Solenoid valve seal material: NBR.
Check the limits for the selected sensor and valve combination. The liquid must remain suitable for operation within those limits. Do not alow water to freeze inside the components.
Installation
- Install the flow sensor and solenoid valve horizontally. Vertical installation is not suitable for this kit and can affect the reading.
- Follow the flow-direction markings and the supplied installation instructions.
- Seal the threaded connections using the specified method. Where PTFE tape is required keep loose tape out of the liquid passage.
- Check the connections for leaks before calibration.
- Calibrate the meter and verify the delivered quantity before normal use.
Current stainless steel sensor design
We phased out the earlier stainless steel sensor because of reliability issues. The old design shown below is no longer supplied.
The photographs below show the newer stainless steel sensor design. The sensor supplied depends on the size selected.
Operation demonstration
The videos show the controller operation and a demonstration of the G1" flow meter.
