12 Water/Wastewater Tide Gauge Promises High Performance & Low Cost
Valeport's (UK) TideMaster, a compact Water Level Recorder, is designed for use in a wide range of fixed or portable survey and tide monitoring operations. Suitable for use in fresh or salt water, the TideMaster is highly accurate and can be deployed for up to a year at a time.
Sales Manager, Kevin Edwards, commented, “TideMaster is an extremely versatile and cost effective new product. It replaces the popular Model 740 and whilst it retains the easy to use features of the Model 740, a lot more enhancements have been made with further provision for additions in the future”.
Low power consumption, with both pre-programmed and a user selectable sampling regime, allow for up to a year of autonomous operation, whilst optional telemetry packages provide capabilities for real time operation. As well as recording water level, TideMaster can be provided with an optional ultrasonic wind speed and direction sensor to record meteorological data.
TideMaster can be set up and data retrieved via an optional control/display panel that uses OLED technology, Bluetooth and an SD memory card. Alternatively, it can be plugged into a PC and controlled using Valeport’s Windows based software, TideMaster Express. This allows the user to download and display recorded or real time data from single or multiple gauges. TideMaster is also compatible with a wide range of Hydrographic software and tools on the market.

Calibrated Infrared Analysers Provide Rapid On-Site Oil in Water or Soil Measurements
Wilks Enterprise (USA) is pleased to announce the availability of factory-calibrated portable infrared analysers for determining the concentration level of oil in water or soil. The InfraCal TOG/TPH Analysers provide easy, on-site measurements in 10-15 minutes and eliminate the need to wait for off-site results. The InfraCal Analysers are ideal for use by non-technical personnel, in refineries or industrial manufacturing facilities and at soil remediation sites.
Factory-calibrated InfraCal TOG/TPH Analyser models are available for using hexane, S-316, or tetrachloroethylene (perchloroethylene) as the extracting solvent -- depending on the customer’s application.
All InfraCal Analysers are portable (operable from a 12 volt dc power supply) and weigh less than 5 lbs. Their compact, rugged design has no moving parts requiring alignment or adjustment and pushbutton, user-friendly operation makes them easy to use with minimal training. The calibrated analysers can display concentrations directly in any desired format such as part per million (ppm) or milligram/kg. A wide range of accessories, such as printer and carrying case increase the versatility and capabilities of the InfraCal TOG/TPH Analysers.

Reliable and Low Maintenance Measurement of Disinfectants
Tests were carried out following the DIN 15839, both under laboratory conditions and in a drinking water installation, over periods of up to half a year; the renowned German institute for water research, IWW in Mülheim, declare the results on linearity, accuracy, precision, and response times to be very good. Test reports are available on request.
The measuring systems of the company Dr. A. Kuntze (Germany) are available for measurement and control of free Chlorine, Chlorine dioxide, and Ozone; apart from the excellent performance, the systems offer many more advantages.
There is a simple installation; with a Krypton K you get all components you need for your measurement mounted on a board and fully wired. Installation is simple; select a representative measuring spot, connect water inlet and outlet, screw in the sensor, and turn on power and water. Within minutes the reading is stable and you can calibrate. This completes the set-up, the system does not need a 24h-period followed by recalibration, as with other measuring systems on the market.

The assembly is equipped with flow alarm, stop cocks at in- and outlet, and a sampling point. The sampling point enables you to take a sample directly at the measuring point. The flow alarm stops the controller in low water situations.
The amperometric method needs no chemicals and produces no waste water. The assembly is pressure-proof up to 6 bar, so the water can be rerouted into tanks or pipes.
The UK’s leading manufacturer of hydrographic and
oceanographic instrumentation.

The sensor used for the disinfectants measurement is constructed of glass and gold, therefore it is robust, easy to handle, and chemically and biologically inert. It has no membrane and needs no exchange of electrolyte. Unlike customary membrane sensors, the electrodes are in direct contact with the water, allowing quick response to concentration changes. A temperature sensor is included for automatic temperature compensation. Selectivity is obtained through the design of the input of the measuring instrument , this design determines whether free Chlorine, Chlorine dioxide or Ozone is measured.
All Krypton systems are delivered with the automatic cleaning ASR. This is an electrochemical cleaning that maintains the electrode surfaces clean and active by electrolysis of water. There is no need for chemical agents or physical components like sand or glass pearls that can get lost or cannot be used in in-pipe installations. Signal loss is prevented by ASR, leading to significantly lower maintenance demand.
The system provides two limit values, above or below these values an alarm is activated and given out via an alarm relay. Two control relays allow dosing of chemicals to maintain the desired disinfectant concentration. The relays can be configured separately, and bi-directional control is possible. Also, the analogue output can be used as controller output. Dosing time is monitored to detect damages in the feed lines and prevent uncontrolled release of hazardous chemicals in case of a defective dosing tube or tube connection. The controller can be stopped by an external switch via digital input, and is automatically stopped in case of failures, low water levels or other pre- determined parameters.
