Mercer Controls Division

...for control panels that work and keep on working!

 

Services

Expert diagnosis and repair of control panels and associated equipment, including flow meters, recorders, automatic dialers, ultrasonic sensors, and fluid level transducers.

Programming

Our staff is very familiar with a variety of Programmable Logic Controllers, Variable Frequency Drive units, Flowmeters, and Level Controllers. We can assist you in establishing operating conditions to meet your requirements.

SCADA

A Supervisory Control And Data Acquisition system can benefit customers by allowing them to remotely receive status and alarm notifications from water plants, sewer plants, and lift stations using the latest Telemetry technology. Plant sites may be miles away from the office. Systems are available which use no telephone line or hardwired connections. Let us talk to you more about this advanced option!

Water Tank Substitution

In areas covered by only one Water Tank we are able to supply water to your customers without anyone being aware that the method of regular delivery had changed.

With the use of a Variable Frequency Drive sized to match the horsepower of your pumps, we can take your tank off-line and still provide your customers with the same water pressure to which they are accustomed.

Flowmeter Calibration

Due to the requirements of the Texas Natural Resource Conservation Commission (TNRCC) most flowmeters at Wastewater Treatment Plants must be calibrated and certified yearly. We have technicians on staff who are qualified to perform this task.

Our calibration rates are reasonable. We charge $275.00 to $350.00 for checking and certifying the calibration of a flowmeter within a 50-mile radius of our office in Edna. Additional flowmeters checked and certified on the same trip are discounted $50.00 each. Additional charges may apply if the round trip is over 100 miles. Please call for details.

If adjustments are necessary there will be extra charges.

Variable Frequency Drives (VFD)

A VFD can control the amount of power that a blower or rotor motor uses to supply Dissolved Oxygen to aerate waste water. A PLC interprets received data and then varies the RPM of the motor/s used in order to maintain the desired D.O. reading. The immediate cost savings in energy will be considerable. An added benefit is extension of the life of the motors.

Temporary use of a VFD during a water tank inspection can save having to run a booster pump at full capacity and save a huge elecricity waste due to water pressure issures. To eliminate this waste, a VFD is connected to your existing pump to control the water line pressure by varying the RPM of the pump as needed to maintain a stable pressure.

Please see our VDF Rental Rate Schedule

Preventive Maintenance

We now offer our customers the benefit of a preventive maintenance program. The best way to eliminate costly repairs is to prevent the equipment from failing in the first place. Budgeting for repair and maintenance is very difficult. You are trying to predict what will break down and when. We will review the condition of your equipment and give you a detailed report of our findings, with our recommendations. Everyone involved in planning for the year can have a better understanding of what repairs need to be budgeted. There is no maintenance program that will insure your machinery will not fail without warning, but the procedures we have created combine our expertise and the use of instrumentation to help identify failures that need immediate repair, as well as accurately flag potential problems.
