WORLD PUMPS
Product news March 2009
Flow rate totaliser from Trimec Trimec has introduced the RT20 Rate Totaliser which has been designed for calculating and displaying flow rates and totals from flowmeters with pulse, sine wave or frequency outputs. The totaliser is available as battery or externally powered and features a large 6 digit LCD total, 8 digit cumulative and 5 digit rate display for easy reference. The RT20 is housed in a strong IP66/67 rated aluminium field
and panel mountable housing making it suitable for more rugged applications. A heavy facia protector shield, relay board with SPDT outputs and flowmeter and pipe mount kit options are also available. Other features and benefits include scaleable universal pulse or frequency inputs, scaled pulse output, long battery life, non-volatile memory and reverse polarity protection. www.trimec-europe.com
Trimec’s new flow rate totaliser in a strong housing.
VFD for water well pumps SJE-Rhombus, has launched the SubCon™ Variable Frequency Drive (VFD) for residential water well pump control. The SubCon VFD monitors water pressure continuously and the drive will automatically adjust the pump speed to maintain a constant pressure. The set pressure, along with other parameters, is easily adjusted via the keypad. It incorporates an alpha-numeric display featuring current pressure in PSI, target pressure setting, pump speed (Hz), pump amps, pump run time and error codes. Advanced protection features include adjustable electronic motor overload protection, over temperature (VFD), high and low discharge pressure alarms, and pressure transducer fault.
The SubCon VFD for water well pump control.
The SubCon VFD is available for 1.5 HP and 3.0 HP 230V applications and is supplied in a NEMA 1 enclosure with a 4-20 mA (0-145 PSI) pressure transducer. Two SubCon VFDs can be configured for duplex applications where the units will automatically alternate and provide lead/lag control. www.sjerhombus.com www.worldpumps.com
