Instruments used in the Agriculture Industry
Agriculture in the UK and Ireland demands precision, efficiency, and compliance with strict environmental and water management standards. From irrigation systems to dairy processing, farmers and agribusinesses rely on accurate measurement and control technologies to optimise resources, reduce waste, and maintain productivity.
This page explores eight key agricultural applications and the specialised instrumentation solutions available from PCT to support these processes. Whether you manage crop irrigation, slurry transfer, or greenhouse operations, our products deliver reliability and performance tailored to the unique challenges of modern farming.
Application Sections
Irrigation Flow Monitoring
Efficient irrigation is critical for crop health and water conservation. UK farms often use boreholes, mains-fed systems, and drip irrigation, all requiring accurate flow measurement to prevent overuse and comply with abstraction regulations. Monitoring flow ensures pumps operate within design limits and helps detect leaks early. Seasonal variability and diverse pipe materials make non-invasive solutions ideal for retrofits. By integrating flow monitoring, farmers can optimise water distribution and reduce energy costs. This application supports sustainability goals and compliance with local water authority requirements.
Relevant products:
- Dynasonics TFX 5000 Ultrasonic Flow Meter - Designed for permanent installation, this clamp-on meter measures liquid flow without cutting pipes. It suits irrigation mains and borehole lines, offering high accuracy and easy installation.
Key benefits:
- Non-invasive clamp-on design avoids downtime.
- Handles a wide range of pipe sizes and materials.
- Ideal for clean water and agricultural fluids.
- Reduces installation cost and complexity.
- Dynasonics DXN Portable Ultrasonic Flow Meter - Perfect for temporary checks and troubleshooting irrigation systems. Engineers can verify pump performance and detect blockages quickly.
Key benefits:
- Portable and battery-powered for field use.
- Works on metal and plastic pipes.
- Real-time data logging for compliance reporting.

Fertigation & Nutrient Dosing
Fertigation combines irrigation with nutrient delivery, requiring precise dosing to avoid crop damage and environmental harm. UK farms increasingly adopt automated systems for efficiency and compliance. Pressure stability and accurate chemical injection are essential for uniform distribution. Monitoring ensures pumps and dosing units maintain correct ratios, reducing fertiliser waste and improving yields. This process supports sustainable farming and meets regulatory standards for nutrient management.
Relevant products:
- Equilibar Back Pressure Regulators - Maintain stable pressure in dosing lines, ensuring consistent chemical delivery.
Key benefits:
- Ultra-responsive diaphragm design for precise control.
- Handles corrosive fertiliser solutions.
- Improves dosing accuracy and crop health.
- Peristaltic Pumps (Longer Range) - Ideal for chemical injection in fertigation systems.
Key benefits:
- Accurate low-flow dosing capability.
- Resistant to aggressive chemicals.
- Simple maintenance and long tubing life.
Dairy CIP Systems
Clean-in-place systems are vital for hygiene in dairy operations. Monitoring pressure and temperature ensures effective cleaning cycles and compliance with food safety standards. UK dairy farms require robust sensors to withstand harsh cleaning chemicals and high temperatures. Accurate data prevents under-cleaning or overuse of resources, reducing costs and improving product quality.
Relevant products:
- PCT Z-Series Pressure Transmitters - Rugged sensors for CIP pressure monitoring.
Key benefits:
- Stainless steel wetted parts for hygiene.
- Wide pressure range for CIP cycles.
- Reliable output for PLC integration.
- Temperature Probes & Transmitters - Ensure correct cleaning temperatures for sanitisation.
Key benefits:
- Fast response for accurate control.
- Suitable for dairy environments.
- Easy integration with control systems.
Crop Sprayer Pressure Control
Consistent spray pressure is essential for uniform application of pesticides and fertilisers. UK farms rely on accurate pressure monitoring to maintain nozzle performance and avoid drift. Real-time feedback helps operators adjust settings quickly, improving efficiency and reducing chemical waste.
Relevant products:
- Pressure Transmitters - Provide reliable pressure data for sprayer systems.
Key benefits:
- Compact design for mobile equipment.
- High accuracy under vibration.
- Compatible with agricultural controllers.
Slurry Transfer Monitoring
Slurry handling requires robust flow and pressure monitoring to prevent blockages and spills. UK farms often pump slurry over long distances, making accurate measurement critical for pump protection and compliance with environmental regulations.
Relevant products:
- Dynasonics TFX 500w Ultrasonic Flow Meter - Non-invasive measurement for slurry-water mixes.
Key benefits:
- Handles challenging fluids.
- Easy installation on existing lines.
- Reduces downtime and maintenance.
Rainwater Harvesting & Storage Management
Rainwater systems help farms reduce mains water use and costs. Monitoring inflow and outflow ensures tanks operate efficiently and comply with water quality standards. Accurate measurement supports sustainable farming practices.
Relevant products:
- Process Displays & Indicators - Provide local readouts for tank levels and flow.
Key benefits:
- Clear visual feedback for operators.
- Simple installation and configuration.
- Improves system reliability.
Greenhouse Climate & Irrigation Control
Controlled environments require precise monitoring of temperature and pressure for misting and drip systems. UK horticulture operations depend on accurate sensors to maintain crop health and optimise resource use.
Relevant products:
- Temperature Probes - Maintain ideal climate conditions.
Key benefits:
- High accuracy for sensitive crops.
- Durable in humid environments.
- Easy integration with automation systems.
Private Water Supply Compliance
Farms with private water supplies must monitor flow and pressure for abstraction reporting and treatment dosing. Accurate data ensures compliance with UK regulations and protects water resources.
Relevant products:
- Dynasonics DXN Portable Ultrasonic Flow Meter - Ideal for spot checks and compliance audits.
Key benefits:
- Portable for multiple sites.
- Quick setup and accurate readings.
- Supports regulatory reporting.
