System temperature control tank with integral modulator valve and flowmeter

In a heat transfer system for temperature control in a manufacturing process, the combination comprising:

• a pump with a case having a pump intake passageway and a pump discharge passageway;
• a first tank receiver on the case and communicating with one of the passageways;
• flowmeter apparatus adjacent the first tank reciever and responsive to the flow into the pump case;
• a first tank received in the first receiver and having an inlet port for coolant from the process;
• a releasable fastener removably securing the first tank to the case;
• a tank discharge port in the first tank at a location remote from the first receiver;
• a second tank receiver on the case and communicating with the other of the passageways;
• a second tank received in the second receiver and having a heater inside the tank;
• a releasable fastener removably securing the second tank to the case;
• a second tank discharge port in the second tank at a location remote from the receiver;
• the second tank receiver communicating with the pump discharge passageway and the first tank receiver communicating with the pump intake passageway, the combination further comprising:
• a modulator valve having an inlet at the first tank discharge port and having an outlet to drain;
• a temperature sensor for fluid passing through the second tank to the discharge port for delivery to the process;
• a temperature sensor for fluid passing from the process into the first tank;
• a controller coupled to one of the temperature sensors and to the modulator valve and operable in response to increasing temperature in one of the tanks to operate the valve to increase flow from the outlet to drain;
• wheels supporting the combination of the pump, the temperature sensor and the controller for mobility thereof relative to the process;
• and
• a display supported by the wheels and coupled to the controller for displaying the amount of water flow detected by said flowmeter apparatus and the temperature of the flowing water.

The combination comprising:

• a first tank having first and second ends;
• a first port in the first tank and remote from the first end of the first tank and having a first mounting surface around the port and lying in a first plane;
• a second mounting surface on the first tank lying in a second plane perpendicular to the plane of the first surface;
• a modulator valve mounted to the first mounting surface and having an inlet at the first port and having an outlet to drain;
• a modulator valve drive motor mounted on the second mounting surface and driving the valve;
• a pump having a case, the first end of the first tank being fastened to the case and the case having an intake passageway;
• a flowmeter received in the first end of the first tank and including a vane rotatably mounted in the first tank;
• a sensor device in a portion of the tank adjacent the vane and responsive to changing distance of a portion of the vane relative to a portion of the device to produce a signal;
• a first tank receiver on the case and communicating with the intake passageway;
• the first tank having its first end received in the first tank receiver and having an inlet port for coolant delivery from the process;
• a releasable fastener removably securing the tank to the case;
• a second tank receiver on the case and communicating with a discharge passageway of the case;
• a second tank received in the second tank receiver and having an outlet port for coolant delivery to the process;
• a releasable fastener removably securing the second tank to the case;
• a temperature sensor for fluid passing through the second tank to the outlet port for delivery to the process;
• a temperature sensor for fluid passing from the process into the first tank;
• and
• a controller coupled to one of the temperature sensors and to the modulator valve and operable in response to increasing temperature in the first tank to operate the valve to increase flow from the modulator valve outlet to drain.
