Aqualarm flow warning device supplier

[superheat6k]

Following the engine seizure on my last boat caused by a fouled cooling water inlet I am now paranoid about water flow and exhaust temperature warning devices.

Aqualarm offer an ideal range of devices in the USA. But does anyone know of either an established UK importer or alternative devices I can consider ?

Thanks.

I installed their raw water flow sensors to my GB42 about 20 years ago, been very happy with them. Paid off when i had a partial blockage from a plastic bag in Italy a few years ago.

Pretty sure i bought direct from them. Extra cost obviously for importing but nothing in the overall picture. Worth contacting them & asking

I have exhaust temp monitors but worry that by the time I shut down the offending engine, the heat will continue to build and engine damage still occur as these are at the end of the cooling system. The flow sensors are at the start of the cooling system so a far more proactive way to manage raw water flow.

Try "marinesparesuk" also known as Trickett Marine. I've fitted Aqualarms on three engines and have found them invaluable because they give an immediate indication that raw cooling flow has been interupted. Long before an overheat can happen.

Why not link the raw water pipes side to side between strainers and raw water pumps? That way a blockage one one side lets both keep cooling.

I do know what you mean - the potential consequences demand knowing what’s going on asap. And we’re only a yacht with a 50hp 4 pot…

But EGTs are very sensitive and would surely show the increased temp almost straight away (with an alarm in under a minute if not 30 seconds). I guess with a mobo at wide open throttle that is still too long?

Fitted Aqualarm in 2013 and am happy.

Since twin engined I got their

20162

SAVE-YOUR-ENGINE KIT MODEL 206 (1-1/2" FPT), TWIN, 12V

directly from aqualarm.net at USD 180 + shipping etc.

If Googling somethin like water flow monitor alarm site:.uk you will find alternatives.

The alarm should be triggered by low/no flow, so the max capacity of your impellers isn't too important as long as the device allows same flow (inner dia) as your hoses.
