With the global biogas market estimated at £1trn and energy security, climate change and the UN Sustainable Development Goals driving the need to rapidly increase the uptake of biogas, UK AD & Biogas and World Biogas Expo 2017 is the place to come to find out why and how. Taking place on the 5-6 July at the NEC in Birmingham, it will be the show’s seventh consecutive year and will consolidate its position as the #1 global trade show for the biogas industry.
This year the show will benefit from its new partnership with the World Biogas Association (WBA) to showcase the global biogas industry at ADBA’s leading event, which last year was attended by participants from over 50 countries.
Exhibitors throughout the combined event will be showcasing all the products and services required to commission, build and operate all types of biogas plant, including agricultural, commercial and sewage treatment plants. The show will also cover for the first time landfill gas and food waste collection systems, as well as everything needed for heat and power networks, and using biomethane in transport.

At Boiswood we stock a wide variety of components to assemble Pressure Reducing and Back Pressure regulators. From the GO product range
we can generally assemble the PR1, PR2, PR7, PR50, BP3, BP8 and BP60 models to your required specification from stock. We would then pressure test the assembled regulators using our Nitrogen gas bottle to ensure they are functioning correctly.
We can provide a copy of the pressure test certification on request. With this considered, it means you could have your regulators assembled, tested and despatched on a next-day service, after the processing
of your order. In order to comply with the BCGA's recommendations of servicing/replacing regulators after a 5-year operation period, many users
call on Boiswood to service their GO regulators. Whether you require repairs for a faulty/broken regulator or just a general service - We will quickly turnaround a detailed corrective action
report and recommendation for any spare parts. We can help to diagnose the causes as to why the regulator may have failed in service, always with
the objective in mind of lowering your costs. Again all regulators are assembled and pressure tested before they are returned to you. We will work closely with you to provide component subassembly and panel solutions suitable for your application. Looking at the example to the left, we will take your required specification and produce a solution for you to sign off on. From there
we can gather all of the necessary components and begin to create a suitable subassembly for your application. Whatever your requirements contact us today for technical consultation.

The electro-optic type level sensors utilise their infrared LED light and receiver to detect. The LED is positioned and directed into a prism
which forms the tip of the sensor. As soon as the media (liquid) touches the prism, it disrupts the light and senses the change. This change
can relay to an electronic switch (ie. actuating an alarm or circuit).
The ultrasonic type level sensors have no moving parts and require absolutely no maintenance. It offers an alternative to the generic
reed switches and are ideal for applications where foam and condensation could affect the sensor. The ultrasonic pulses emitted reflect
off liquid surfaces and the gap area therefore detects its presence or absence.
The capactive sensors are specifically calibrated to each medium, in order to account for a number of variables. They can be used on aqueous
and non-aqueous fluids regardless of transparency or colour. Once the factory preset or customer-set trigger point is actuated, the sensor
can then switch to the required output.
The float sensors operate on perhaps the most common and simple principle on the market. As the float rises or lowers, the magnetic field actuates the
encapsulated reed switch to its required setpoint. Depending on design these can be mounted vertically or horizontally.
This is also referred to as guided wave radar or guided microwave. Very similiar to the ultrasonic principle of operation, except these pulses can
travel up to the speed of light. This provides a very high accuracy and repeatability for the users.

Model 209H Features:
- Rugged 316L SS Construction -The sensor and all wetted material of the 209H are manufactured using a 316L stainless steel, enabling the sensor to stand up in corrosive applications.
- Flexibility For Many Applications -The Model 209H transducer offers many pressure and electrical fittings, covering many installation configurations. The units non-oil filled design makes it ideal for the alternative energy market
- Accurate and Reliable -The Model 209H is designed and built to withstand demanding applications. The unit comes standard with an accuracy of ±0.25% FS across a wide pressure range offering, providing high performance at a low cost.
Setra’s new Model 209H is designed with all 316 stainless steel wetted materials eliminating the risk of hydrogen embrittlement. The transducer is offered in a variety of pressure ranges and electrical fittings to meet a wide range of installations and applications.
Hydrogen embrittlement is the process a material goes through when it comes in contact with forms of hydrogen. This process causes the material to lose ductility, making the material brittle and prone to the propagation of fractures and cracks in the material. These cracks may allow hydrogen to pass through a diaphragm or surface into the sensor or surrounding area posing potential safety risks as well as contamination of the system.
What are the different types of pressure transducer?
Chemical Vapour Deposition
The Chemical Vapour Deposition method involves bonding a polysilicon layer to a stainless steel diaphragm. This is done at the molecular level to produce a sensor which then has a superior long term drift performance. Semiconductor manufacturing processess are used to create a polysilicon strain gauge bridge with superior performance at a very cost-effective price. Chemical Vapour Deposition units are the most popular sensor for OEM applications construction as they can offer excellent price and performance.

The Capacitance Type is used for a large variety of high volume OEM bespoke applications. Measuring capacitance change between two surfaces allows for transducers to detect very low pressure and vacuum levels. Their extremely robust construction lets capacitance units to be used in a huge range of applications. They offer great price and performance benefits.

Sputtered Thin Film
Sputtered film deposition creates transducers with maximum combined linearity, hysteresis and repeatability. These types of units allow for extremely high full scale accuracy and very low long term drift. Accuracy is as high as 0.08% full scale with long term drift as low as 0.06% full scale per year. They are most commonly used in critical applications where precision is a must-have.

Sinking and sourcing are terms used to describe how a load (the device being turned on or off) is powered in regards to the sensor.
Sinking is the most common and it involves the switching of load current (power) supplied by a power source external to the sensor. With this configuration, current passes through the load first, through the output switch of the sensor second and finally to ground. Sensors with sinking output switches the negative leg of the circuit.
Sourcing refers to a configuration in which the sensor is the source of the current required to power the load. In a sourcing situation, current supplied by the sensor passes through the load second and then to ground. Sensors with sourcing output switches the positive leg of the circuit.
Wet sink - The load is energised as long as the sensor tip is immersed in fluid.
Dry sink - The load is energised as long as the sensor tip is dry (not immersed in fluid).
