Turbine Flowmeters
Titan’s small turbine flowmeter range use a radial flow principle based on the Pelton wheel technique. This well proven method is the ideal way of measuring low rates of flow of low viscosity liquids. For these mini flowmeters, a jet of fluid is directed at a turbine that is mounted on robust low friction sapphire bearings. The geometry of the turbine and the fluid chamber ensures that the rotational speed of the rotor is proportional to the flow rate through the device. The use of this radial arrangement allows more energy to be imparted into the turbine, so the bearing drag is far less important. Furthermore, because more energy is available the bearings themselves can be a lot stronger so increasing the life of the flowmeter. For larger flows, some of the liquid can bypass the turbine chamber, which then behaves as a “shunt” to the metered fluid. Accuracy is still maintained and the output remains linear.

Slip-Ring Motor Starting Panels
Rotor Starter
The Slip-Ring Motor Starters are based on the series of resistors that are applied to the rotor circuit to control the speed/torque characteristics of the motor. Rotor starters are mainly used for the motor starting applications requiring high-starting torque like loaded belt conveyors in mining industry. By external resistors, it is possible to shift the motor maximum (break-down) torque up to starting torque point for motors under heavy loads during start-up. The resistors are splitted into some steps and controlled via contactors by motor starting control system. As the motor speed increases, the external rotor resistors are eliminated by shorting contactors until all external resistors are shorted out.
