Hello again Dennis and thanks for your reply. To be honest I only dipped my toe in here earlier in the year and forgot about it! The application now is, as then, a controller for our 'fancy' compost toilet. One of the elements is a level monitor for a urine container and I was playing around with a capacitive sensor approach but it proved unreliable. I've since realised that weight measurement can be made to work (I need to mount the sensor in such a way that the bottle is only raise a few mm. in this approach I'm only planning on putting the sensor under one edge as it's the relataive volume I need to, initially, display o LEDs with a 'full' warning buzzer. Later i may add one of those neat low-power sharo displays.
