## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=SS314990619:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/SS314990619:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

## Description

The Liquid Level Sensor measures the height of water or other liquid and converts it to the voltage signal. It works with a data logger or other devices that have analog voltage input ports.

The Liquid Level Sensor has a built-in silicon piezoresistive core that features high sensitivity. The internal chip converts the millivolt signal into a standard voltage signal, which can be connected to a computer, a control instrument, or a PLC.

It's small-size and lightweight, easy to install. With a sealed stainless steel probe, it can work in water, oil, and mild-corrosive environments. The sensor has high anti-vibration and anti-impact performance. It can be widely used in process control, aviation, aerospace, automobile, medical equipment, HVAC, and other applications.

**Features**
