Abstract

Liquid flow sensors connected to an engine or power means requiring liquid cooling. Sensors measure liquid flow velocity and volume factors on a visual flow gauge in increments of low, medium and high volume readouts in conjunction with a warning means, for liquid flow and pressure indication.

Claims

1. A monitoring device for determining the condition of an engine cooling system comprising:

An engine having a liquid cooling system;

a sensor body mounted in liquid communication with said cooling system;

a flow responsive element mounted in said sensor body;

a first sensing means actuated by said flow responsive element for producing an electrical signal indicative of no flow of engine coolant;

a second sensing means actuated by said flow responsive element for producing an electrical signal indicative of the flow rate of engine coolant; and

indicator means attached to said first and second sensing means.

2. Apparatus as in claim 1 and further including a pressure sensing means in the sensor body and indicating means connected to said pressure sensing means.

3. Apparatus as in claim 1 in which the sensor body is in the form of a unitary structure having a single threaded fitting for attachment into the cooling system.

4. Apparatus as in claim 1 in which the sensor body is in the form of a unitary structure having inlet and oUtlet parts for attachment into the cooling system.

5. Apparatus as in claim 1 in which the engine is a marine engine having a sea water cooling system.

6. Apparatus as in claim 1 wherein the indicator means attached to the flow responsive element includes dial means for continuously indicating the coolant flow, said dial means being calibrated to show low normal and high readings of coolant flow for said engine.

7. Apparatus as in claim 1 in which the indicator means is mounted at a point remote from the engine and said indicator means includes warning lights and an audio alarm means.
