LNU Level Sensors 
~Battery Powered~

The LNU range of wireless ultrasonic level sensors are designed for water level monitoring and flow measurement and are suitable for a range of applications including water and waste water, CSO monitoring, remote tank monitoring, flood warning systems and bin management.

These ATEX approved level sensors feature a replaceable lithium battery and a large memory which can record up to 500,000 measures. Multiple wireless communications options are available allowing for easy remote data collection and viewing, including Avelour wireless software or the ljitrack web platform using GSM/GPRS.

Available with a range of different options including Modbus, 4-20mA, pulse and digital outputs, these sensors feature a measuring range of up to 10m, depending on the model. Housing material includes ABS 20% FV with an IP68 enclosure protection making the sensors ideal for use in hazardous environments. Models feature an operating temperature of up to 85°C, dependent on model.
Fluidwell F-Series

The Fluidwell F-Series displays are so robust that they can withstand being run over by a truck

Fluidwell products are the ideal choice for a wide variety of flow metering, batch control and process measurement applications, with a selection of easy to program models and a comprehensive list of options to choose from.

Merry Christmas!

For the third year in a row, we have dug out our favourite Christmas knits and gladly taken part in Save the Children's annual Christmas Jumper Day!

The money raised from the event helps saves children's lives around the world. Donating just £2 could potentially bring essentials like health care, education, protection and food to children who are missing out on the most basic support. Information on the organization can be found here.

We would like to take this opportunity to wish you a fun and festive Christmas and a happy new year!

Flow Monitors & Switches
for visual indication and control

Ideal for observing and monitoring fluid characteristics such as direction, flow and colour during process conditions, sight indicators are a cost-effective way to visually monitor flow and determine if any problems exist along the process line. Available in a choice of designs and materials there is an option to suit most applications.

The rising ball and spinner models are low cost sight indicators that meet the needs of simple flow applications. The rising ball model features a durable PTFE ball inside a borosilicate glass dome. As flow in the pipe rises the ball inside the dome will lift out of its socket, clearly becoming visible. Constructed from durable materials the rising ball model can also be used with chemicals and is available in sizes ¼” to 1 ½”. The spinner model features a PPS plastic spinner which starts to rotate once flow has commenced, this can be from as low as 0.7 lpm. The spinner design can be mounted both horizontally and vertically and is available in sizes ¼” to 1“.

The flap and spout sight flow indicators are a double window range, most useful where visual inspection of the pipeline content is needed. The sizable windows allow an excellent view of the conditions in the line, available in sizes ¼” to 2” and with screwed or flange connections.

The mechanical pointer flow monitors feature a spring loaded valve plate which is deflected proportionately to the flow in line. A mechanical pointer indicates the flow on a calibrated scale with the option of switched set points. The mechanical pointer flow indicators can be installed in any orientation and have screwed, flanged and now wafer connections options. Available in sizes 1/4” to 12” and flow rates up to 5000 lpm.

Siargo MFGD
Natural Gas Flow Meters

Turbine and diaphragm gas meters have traditionally dominated the gas metering market but with integrated MEMS sensing technology the MFGD Mass flow meter has inherent advantages over these legacy technologies.

Specially designed for natural gas metering, the MFGD substantially reduces metering accuracy losses caused by temperature and pressure variations in the system, as they compensate electronically for this volumetric expansion using the world’s leading, patented MEMS technology. Further advantages over traditional gas meter models include; extremely low pressure drop, low power use and a field replaceable long-life  battery.

The MFGD includes optional pulse output and RS232 for remote communications . The large integrated data logging memory allows for easy historical data download and analysis. The meter is available in aluminium with BSP threaded or counter-flanged connections and comes in sizes DN32 to DN80 with a flow range of 0.1 to 500 Nm3/hr, ideal for light industrial gas measurement applications.
