What is a flow sensor?

Flow sensors can be purchased at any reputable distributor, such as RS Components and are used for:

  • oil and gas 
  • solvents and chemicals
  • drugs 
  • industrial coolants 
  • steam 

 

Which type of flow sensor is right for my business?

Water flow sensor

As the water passes through the sensor, the turbine is rotated sending a signal to the wire coil attached.  The speed of the water passing through alters the speed the paddle or turbine is turned, providing a measurement of water flow. 

Magnetic-Inductive Volumetric Flow Meters

As conductive liquid flows through the magnetic field, a voltage signal is created, with the signal increasing with the speed of the flow. 

Thermal Mass Flow Sensor 

Capillary Thermal Mass flow meter

Gas diverted through a narrow tube is measured via signals between two PRTD coils attached to the tube. The difference in the signals travelling either with or against the current is directly proportional to the flow, providing a measurement of the mass of the gas flow.

Immersible Thermal Mas flow meter. 

A temperature sensor which measures the internal gas temperature and a velocity sensor are inserted through the piping into the flow with a constant differential maintained between each.  The heat from the velocity sensor transfers to the gas molecules as they pass.  The electrical wattage that is required to reheat the sensor is proportional to the mass flow rate providing an accurate measurement of total gas mass flow rate.   

Transit Time flow measurement 

A transducer emits an ultrasonic beam into the passing fluid which is reflected off present solid particles or air bubbles to the receiving transducer.  The frequency that the reflected beam is received measures the flow, as the frequency shift is linearly proportional to the flow rate.  

To measure flow that does not have bubbles or solid particles, the two transducers are placed on each side of the pipe diagonally opposite. The speed of the beam return changes according to whether the stream is going with or against the flow.  If the flow has stopped, the beam will travel at the same speed in both directions.  

 

Vortext shedding flow sensor. 

A blocking body inside the pipe causes vortices to form which then create zones of low and high pressure known as the Karmen Vortex Street.  A mechanical sensor detects changes in the pressure of the liquid measuring the flow by counting the vortices as they pass.  The difference between the vortices corresponds with a defined measurement of the fluid.

 

Choosing your flow sensor 

Ask your supplier about the most efficient type of flow sensor that will suit the velocity, viscosity, conductivity and  purity of your liquid or gas flow.  Higher quality flow sensors provide reliable data which will ensure that any issues with the liquid flow are immediately detected and preventative maintenance applied.  Discuss your needs with an expert to get the most accurate and efficient use out of your flow sensors. 

 

Neos launches smart leak and smart motion kits. #Neos #NeosSmartHome #NeosSmartKit

New research released today has revealed one in three Brits (21.5 million people) have experienced a leak in the last year. With the average leak costing £632.80, this has cost the nation an eye-watering £13.6 billion. In the longer term, 44.77 million UK residents have experienced a leak in their current or past home.

The research, conducted by Neos is aiming to raise awareness of the damage that leaks from taps and pipes can cause. Many people don’t take precautions against this threat – only one in ten Brits have equipped a leak detector and 11% don’t have insurance – because it is a hidden problem that often only comes to light when it’s too late and the damage is done.

NEOS BOOST

London is the UK’s leak capital, with a shocking 81% of people experiencing a leak in their current or previous home. However, Scots are the most likely to have experienced a leak in the last year (38%). Homes in the South-West of the country are the most leak free, with nearly half (41%) of residents saying they’ve never experienced a leak from a pipe or tap.

 

Interestingly, the data also revealed people living in council housing are less likely to experience a leak – with 52% of homeowners and 55% of private renters experiencing a leak in their property, in contrast to just 42% of those living in a council house.

Including costs covered by individual’s insurers or landlords, leak repair forced Brits to cough up an average of £632.80 per incident, although the research found that it can cost individuals up to £12,000 to repair the damage. Leak victims in Northern Ireland tend to pay the most (£724.40) to fix the damage and those in the East Midlands are most likely to nab a bargain, only paying £424.70 on average. As well, while 30% of those who had experienced a damaging leak had the cost completely covered by their insurance, shockingly 24% of people ended up paying for all of the repairs themselves because they didn’t tell their insurer, perhaps because they didn’t understand their policy or feared being penalised.

 

Matt Poll, co-founder and CEO, Neos says, “Leaks in the home are an incident that many of us don’t think about until they happen. The data has proven, however, that they actually affect most of us. Try asking your friends and family about their experiences – you’ll be surprised at how many have suffered a damaging leak, and at a significant cost to the person if they don’t have insurance.”

 

He continued, “While these findings are worrying, I hope they empower people to seek out options to actively protect their homes from leak damage. Installing leak sensors means that even if a single drop of water is where it shouldn’t be, you will know straight away and be able to act before real damage is caused. There are also other simple steps you can take to protect your home, like switching off your water when you’re out for more than a day or not running water consuming devices, like washing machines and dishwashers, when you’re not home.”

NEOS CAMERA REVIEW 

Neos launched its new Smart Kits, an integrated Smart Leak Sensor Kit and Smart Motion Sensor Kit,on the 22nd July, 2020. The Smart Kits will be for sale via Amazon fend of July and via Dixons and Very in August. The products are great value, coming in at one third of the price of other industry leaders.

 

The Smart Leak Sensor Kit  is designed to detect a single drop of water, preventing small leaks from turning into big problems. It also alerts you to unexpected changes to your home with built-in temperature and humidity sensors. The Smart Motion Kit can capture movements with the Neos Smart Motion Sensor and make any household item smart, from your cat flap to the cookie jar, with its contact sensor. Both kits integrate with the Neos SmartCam, converting it into a  bridge so you can connect all your devices wirelessly and manage them from a single app to check up on your home from wherever you are in the world.

Neos Smart Leak Sensor Kit features:

  • 3x Leak Sensor

  • Built-in Temperature Sensor

  • Built-in Humidity Sensor

  • 1x Smart Bridge

  • Built-in battery Life Indicator

 

Neos Smart Motion Kit features:

  • 2x Open/Close Sensor

  • 1x Motion Sensor

  • 1x Smart Bridge

  • Built-in battery Life Indicator

We will have our review soon.
