Controls and Automation

Pump Control Panels are used to control pumps, their usage and can feature monitoring, warning alarms and can be linked to BMS. They are often incorporated with a display panels and can be housed in weather proof kiosks for easy access.

Made in Britain

Our portfolio of products is extensive which includes our own UK manufactured Level Controls Float Switches and our SEER Monitoring that reduces the risk of unexpected pumping system failure.

 

The SEER monitoring system allows T-T to monitor your pumping stations and plants 24 hours a day and 7 days a week, with live status views and alarm activation. Our monitoring also gives historical data so that we can identify any possible issues quickly.   

  • Wide range of standard products incorporating small starter panels, to multi-motor MCC’s and control suites.

  • Control systems incorporate many different starting methods, Direct onLine, Star-Delta, Soft Starting and Variable Speed Drive.

  • Familiar with all types of level control from straightforward float switches, to ultrasonic, radar, and pressure transducer level detection, either operating on simply start/stop through to fully automated PID (proportional integral derivative) and continuously modulating control.

  • Skilled in a wide range of automation applications and process control, including fluid handling and transfer, batching and vessel fill control systems, and conveyor /materials handling systems, incorporating.

  • PLC system builder, experienced in all major market leaders of PLCs, Siemens, Allen-Bradley, Omron, Schneider Automation, Honeywell, ABB, providing systems with HMI’s and SCADA interface capability, allowing remote data acquisition.

  • Associated ancillary products available from stock including our UK manufactured range of level control Float switches and Ready Level installation equipment, Smart and Press range of pressure control units, level control conductivity probes, and both free-standing kiosks in GRP and mild steel options, and wall mounting housings in polycarbonate versions.

  • Full range of monitoring systems, starting with our entry-level user-friendly Alert both with and without battery backup and volt free contacts for remote devices, through to our innovative SEER range of cloud-based real-time monitoring allowing predictive maintenance and performance trending of equipment and motors.

  • All of this is backed up by TT’s highly skilled, dedicated team of Design Engineers, using the latest design techniques for both the production of schematic wiring diagrams and the construction integrity of the products produced.

  • Innovators of new products, which are rigorously tested prior to introduction to the market, calling on our years of expertise.

  • Fully equipped Test facility ensuring all products meet the specifications required, and our stringent Quality Assurance procedures. 

  • All documentation is completed and recorded using the latest technology. 

Choosing The Best Level Control Solution

With a wide range of choices available for indicating and controlling levels including float switches, ultrasonics, conductivity probes and vibrating forks to name some, the decision will rely upon multiple factors including the medium or fluid sort, required accuracy, ruggedness /durability and of course,  budget.

The principal thing however to think about while choosing a level control arrangement is the medium it will be introduced in or used to gauge.

Water Applications

For water applications, we need to establish if it is potable (drinking water) or waste/dark water.

Float switches are great for both clean water and wastewater applications. They are quite possibly the most well-known arrangements, offering simple easy to install and set up level control and indication.

Conductivity level control arrangements also loan themselves to generally clean or grey water applications but must be installed where the danger of solids clinging to the conductive poles is limited and the risk of debris obstructing the probes is inconsequential.

Corrosive Liquids and Viscous Mediums

'Non-contact' level control arrangements, for example, ultrasonic is particularly fit for corrosive fluids, for example, those utilized in process control. This principle of level control is based on an ‘echo’ being ricocheted from a datum surface and timed until the signal is received to determine the level.

They are suitable for exceptionally thick, dense mediums where float switches would suffer as a result of the specific gravity of the liquid, and contact with any measurement and control apparatus would be counterproductive.

Powders,  Foams and Vapours

Working with powders and foamy liquids presents different issues, for which either tuning forks or radar sensing can give the best level control solution.  Radar lends itself also alcohol level control where gasses and vapours can be present.  In some instances, Radar level control can be installed external to the tank as it can ‘look through’ certain plastic tanks, again offering a safe alternative to potentially dangerous atmospheres.

Budget

Both float switches and conductivity level controls are moderately reasonable as far as expense, with floats being the most cost-effective in most scenarios. The utilization of conductivity probes will require additional costs of a control relay which can be expensive to incorporate into the existing control set-up.

If you have the budget then, Ultrasonic 'non-contact' level control, Radar, or tuning fork type level control is an ideal option as they are the all-round choice due to their longevity and flexibility.

Conclusion 

It is critical to weigh up the expense of the arrangement versus the elements that are required for the application.

Assuming it is an instance of a basic on/off activity like turning on a pump, or initiating a solenoid valve, then, at that point, financially savvy floats or conductivity probes give the best arrangement.

Should incredibly precise level readings be required, or volume estimation of tank substance, then, at that point, Ultrasonic or Radar level control is the clearest decision.
