Electronic flow meter for GH 26

Product detailed description

This electronic flow meter is used in conjunction with the GH 26 regulator to monitor and manage the performance of solar heating systems. Typically found in residential and commercial buildings using solar thermal technology, the device is installed in closed-loop solar circuits where thermal fluid circulates between collectors and storage units. It enables installers to assess real-time thermal efficiency, detect anomalies such as insufficient flow, and ensure the system operates within expected parameters. The unit is commonly used in systems where solar energy is integrated with conventional heating to optimise overall performance.

Installers working with solar thermal systems will find this device essential for commissioning and ongoing diagnostics. It is typically mounted in accessible locations along the circulation loop to allow for regular inspection and troubleshooting. The unit requires careful alignment with the GH 26 control system to ensure accurate data transmission and fault detection. Proper installation ensures reliable long-term monitoring of system performance.

Technical parameters

Installation and connection

Installation involves positioning the flow meter in the primary circulation line of the solar system. Ensure that the sensor is placed in a straight pipe section to avoid turbulence affecting measurements. Use appropriate sealing methods for the electrical connections to prevent moisture ingress. Check that the wiring is compatible with the GH 26 regulator and that all connections are secure and insulated. Common installation errors include incorrect orientation of the sensor and poor grounding, both of which can lead to inaccurate readings or system faults.

Compatibility and accessories

This electronic flow meter is specifically designed for use with the GH 26 regulator. To complete the system, ensure that the regulator is correctly configured and that all required electrical components are in place. Additional components may include wiring harnesses and mounting brackets, depending on the system layout. Refer to the manufacturer’s documentation for full compatibility details.

Technical background for designers

The device operates by measuring the flow rate of the thermal fluid and sending data to the GH 26 regulator, which calculates thermal efficiency. The sensor is constructed using durable materials suitable for use in closed-loop solar systems. Integration into the control system requires attention to signal compatibility and power supply requirements. Long-term efficiency depends on correct installation, stable operating conditions, and regular system checks to prevent sensor drift or contamination.

Service and operation

Regular visual inspections should be carried out to check for signs of wear, corrosion, or blockage in the sensor area. Ensure that the electrical connections remain intact and free from moisture. While no specific service intervals are provided in the brief, routine checks are recommended to maintain system accuracy. Faults such as no flow detection should trigger diagnostic alerts, allowing for timely intervention.

Frequently asked questions

Can the flow meter be used with other regulators besides the GH 26?
No, it is specifically designed for use with the GH 26 regulator and may not provide accurate results when used with other models.

Is the flow meter suitable for outdoor installation?
It should be installed in a protected location to prevent exposure to weather and moisture, as per the manufacturer's recommendations.

What happens if there is no flow detected?
The system will signal a fault through the GH 26 regulator, allowing the installer to investigate potential issues such as pump failure or blockages.

Does the flow meter require a separate power supply?
It is powered through the GH 26 regulator, so no additional power source is required during normal operation.
