Float Switches and Liquid Level sensors are used to determine the level of liquid present/absent in a container. Accurate, reliable, and often low costing, SMD Fluid Switch has a variety of sensors that can help your application to successfully run. In addition to measuring liquids, a float switch can control a pump, activate an alarm and even be used to control another electrical device.

Monitor rising liquid levels when a pump is activated (switches it on) when a threshold is met. Once the level is no longer determined by the switch, the pump will turn off again and continue monitoring for the next occurrence, this technique is used for things like flooding in homes/businesses. Engineers opt for the devices not only because they can be mounted in different ways and made of materials for use in different environments, but also because they are durable and can do the intended job for a great number of cycles with little need for maintenance.

Factors to consider when choosing a Liquid Level sensor

For the most accurate liquid level measurements determining the fluid used in the application is a key factor because different fluids have different characteristics. For example oil and grease are high viscous and require a different sensor than say a sticky or corrosive material. Even specific liquid gravity plays a roll in the choice of sensor. The layout of the liquid containing vessel is also important, thinking of mounting and the temperature, pressure requirements, and even elements like vibration. All these considerations help to achieve the most accurate measurements possible.

Conditional factors are a key consideration like would your sensor be submersed in the fluid, would you like to continuously monitor the liquid level or would you like to switch on and off monitoring. Thankfully our sister company, Fluid Switch has an extensive selection of standard fluid switches in multiple materials to help assist in application needs, more importantly being an OEM, they have the ability to create custom sensors that fit any unique requirements.

This module was custom built by engineers at Strain Measurement Devices for multiple reasons: to highlight a number of different sensors offered by the company, to feature the way sensors can be easily custom built into housing units with multiple sensor and application functions, as well as showcasing how each sensor works independently and as a part of a unit. 

The Air-In-Line Detector is used in this unit with with a siphon pump that moves the liquid from one chamber to another,  when the liquid is removed from chamber one, the detector signals there is air in the line and switches the pump to chamber two. Next is the combination Bubble and Occlusion sensor that detects air in line and any pressure build up in the tube, like pinching or a blockage in the line, if either event occurs the pump shuts off completely and has to be manually restarted. This unit comes equip with a dial to introduce bubbles into the line and a clamp to cause a blockage in the line to demonstrate how the sensor reacts.  The final demo sensor is an optical liquid level sensor that uses ultrasonic technology to sense the level of water, signalling the need to switch the pump from one chamber pump to another.

Strain Measurement Devices offers a vast portfolio of standard and custom made sensors for applications across almost every market. With six growing product lines we are able to solve many needs, in special housing and packaging that works best for your needs.
