Water metering - Import export

Thorne & Derrick International, based in the UK, are leading Specialist Distributors of Metering products for commercial, industrial and hazardous area applications – we supply meters for water, gas and heat (thermal energy) metering from leading manufacturers in a range of technologies including Ultrasonic, Clamp-on, Diaphragm, Rotary, Turbine, Electromagnetic (Magmeter) and Woltmann. We provide excellent customer service from our trained sales engineers specialising in recommending the optimum meter to ensure the highest accuracy and reliability of measurement – we can recommend meters to ensure compliance with approval and regulatory schemes including RHI, MID and WRAS and also specify metering products to achieve BREEAM credits for sustainable buildings.

Water meters using the multi-jet principle are the best cost/performance, long life, flow measurement instruments. Our water meters offer wide clearances in the measuring chamber and negligible area of contact between static and moving parts. It is these characteristics which are the main reasons for the high reliability of this design even in hard water.

Choose from Arad’s flagship ultrasonic bulk meter, the Octave, with no moving parts, lifetime high accuracy and no maintenance required. With batteries that last up to 15 years. Or Arad’s Woltman meter with the unique sliding bearings that ensure substantially longer lifetime. The WSTsb has a wide measuring range. AMR configuration available

Water flow calibration services to ISO 17025 and UKAS accredited, covering 1 cc/min to 1000 l/min. Uncertainty measurement from 0.1% of reading.

The Round Lead Seal is designed with two parallel holes and a knot chamber. During fitting the wire or string is threaded through the two parallel holes and crossed inside the knot chamber before closing with the sealing tool to prevent slippage. The LS31F Seal Cross-hole Lead Seal is designed so that the lashed wire is crimped together when the seal is compressed with the sealing tool. The effect of crimping the lashed wire together alleviates any chance of twisting the wire out of the hole without leaving clear evidence of tampering. To optimize security the sealing tool dies can be engraved to emboss or deboss characters /numbers/logo onto the seal so giving reference to the application user. Recommended applications Gas, Water & Electric meters, Drums, Valves, Refineries, Post Bags, Cages, Lockers. Material 99.9% Pure Lead ** Click for more **
