Water / Wastewater 41 New contract
helps protect water resources
Photometer series now includes Bluetooth® technology
The MD 610 and MD 600 Photometers from Tintometer are easy to operate, portable devices, with a modern design and the analytical features of laboratory photometers.
All important water analysis parameters from A(luminium) to Z(inc) are measured by these two instruments. Combined with the high precision of Lovibond® reagents, a reliable and quick analysis of water samples is guaranteed. Reagent tablets, powder reagents, liquid reagents or cuvette tests are used depending on the method.
Six long-lasting LEDs serving as a light source in combination with interference filters guarantee the highest precision. The devices are designed without moving optical parts and thus have a maintenance-free measuring unit. Up to 500 data records can be stored in the MD 610, 1,000 data records in the MD 600.
The AquaLX® app, which is available free of charge for AndroidTM and iOS®, enables the MD 610 to transfer measurements to smart phones or tablets via Bluetooth®. The data
management then enables analysis and export as a CSV file or graph via email.
These instruments, housed in a waterproof case, feature a clear display with background lighting, automatic selection of wavelength, more than 120 pre-programmed methods, the availability of more than 35 user-specific methods and buffer for up to up to 1,000 data records. The user guidance facility is available in German, English, French, Spanish, Italian, Portuguese (BR), Polish, and Indonesian
The tried and tested MD 600 photometer uses the classic infrared interface with which data can be transferred by means of the IRiM module to the PC or laptop.

The Environment Agency has awarded a 4-year contract to Meteor Communications for the provision of telemetry systems, services and MeteorCloud data hosting for water quality monitoring systems located in English rivers and bathing waters.
The contract was awarded on 7th June 2019 and ensures continuity of data from around 250 real-time water quality monitoring outstations. Monitoring Services Team Leader of the Agency’s National Laboratory Service, Frances Houston said: “We are now working with Meteor Communications to establish a highly effective and flexible monitoring capability that enables us to deploy real-time, remote water quality monitoring stations at almost any location. We now have the tools to better understand the dynamics of our water environment and provide our scientists with a rapidly deployable monitoring capability with which to detect a wide range of inputs to our rivers and streams.
“The kiosk systems are generally employed for longer term catchment scale monitoring whereas portable ‘suitcase’ systems enable the Agency to provide agile short term investigation and pollution response at a moment’s notice.”
All of the systems utilise 3G/GPRS roaming communications; providing 24/7 web-based access to high resolution water quality data. This provides the Agency with timely, cost effective and meaningful evidence helping to focus resources where they are most needed.
The outstations covered by the contract are ESNET (Environmental Sensor NETwork) modular monitoring systems, developed by Meteor Communications. The company’s portable and kiosk-based water quality monitoring systems employ multi-parameter sondes that can either be deployed directly in the water or installed in a specially designed chamber through which extracted water is pumped. Typical systems measure ammonium, pH, conductivity, temperature, dissolved oxygen and turbidity, with options for several other parameters including chlorophyll, and nitrate. Sondes are exchanged on a monthly basis and returned to the NLSi laboratory where they are serviced and calibrated before redeployment.

Expressing his delight with the award, Matt Dibbs, Meteor’s Managing Director, said: “Through continued development of our ESNET modular monitoring platform we are able to meet the Agency’s need for robust, reliable real-time data collection from any location. This gives us the ability to meet the requirements of anyone wishing to monitor water quality in rivers, wastewater effluent, lakes, reservoirs and bathing waters.”

The In-Situ Water Level Meter, available in the UK via Bell Flow Systems, provides a range of easy to read dip meters which are perfect for professionals working in groundwater monitoring sector. The Water Level Meter 200 is manufactured using high-tensile steel with stainless steel conductors which makes this range highly durable and accurate. The water level tape is ASME- certified and housed in a protective polyethylene jacket which alsoenhances the durability and longevity of the tape in the field. The Water Level Meter 100 offers an economical option, using a Kevlar reinforced polyethylene tape and stainless steel conductors. This range of water level meters also ue an IP68 probe so they can be fully submerged to find the bottom of a well or borehole.

The meter is ready for effective, accurate fieldwork and was designed with this in mind. A key feature of the water level meter is that is has both static and drawdown modes to perform low-flow and pump tests. With its integrated well hanger, the base unit will stay secure and ensure the tape of the water level meter is not damaged by abrasion on the well case.
It is ergonomically designed to make it easy to unwind and rewind the tape, as well transporting on site. Additional features include a safety disconnect design on the tape that can disengage the probe if it were to get trapped inside the well. A probe can be replaced easily in the field so there is no need to return the tape to us for repair.
In-Situ’s water level meter has a high strength tape so there is less stretching, which improves both the repeatability and accuracy of your measurements. A sensitivity dial on the reel allows for compensation of incorrect readings caused by cascading water.
Bell Environmental recently provided a client with a 300m (1000ft) long Water Level Meter 100 for a depth to water measurements. The flexibility of the level meter means that any lengths from 30m (100ft) to 600m (2000ft) can be requested, all offered with a 5 year warranty.
