Tech-Tipp: OTT netDL Configuration with several SDI-12 Sensors

All new OTT sensors  provide a bus-capable interface, either SDI-12 or the RS 485 based OTT SDI . The special Master Modul of the OTT netDL enables the connection of several sensors to every bus (SDI-12 or OTT SDI). Connect for example an OTT Pluvio² and a Lufft WS510  sensor to one OTT netDL and you get a compact, efficient weather station. Just talk to your personal contact at OTT Hydromet to learn more.

The following Tech-Tipp shows exactly how you connect several SDI-12 sensors to an OTT netDL step by step.

OTT Hydromet sensors for measuring water level in creeks and bayous, played a critical role during Hurricane Harvey.

Blog-Harvey-US

Hurricane Harvey, and the subsequent flooding, was an unprecedented and devastating event in eastern Texas. Harvey produced an average of 33.7 inches of rainfall over the 1,777 square miles of Harris County over a 4 day period which equates to 1 trillion gallons of water and is also 68% of the yearly annual rainfall. Of the 22 watersheds across Harris County, 13 established new record water levels during Harvey surpassing previous records by Tropical Storm Allison (2001), Tropical Claudette (1979) and the @016 Tax Day flooding. The Harris County Flood Control District was first established in 1937 following two major floods within six years and started installing their Flood Warning System in 1982 and was at the epicenter of the flooding associated with Hurricane Harvey.  Since 2010, the District has partnered with OTT Hydromet to expand their real time network, and install various sensors which measure water level responses in creeks and bayous. Water level measurements provide critical information needed by first responders and the National Weather Service when making decisions on issuing targeted flood warnings and properly messaging needed actions.

What does the RoHS certification mean for OTT products?

RoHs_OTT

The EU Directive 2011/65 / EU is intended to limit the use of hazardous substances in electrical and electronic equipment. Since 22 July 2017 the RoHS regulation is applicable to monitoring and control instruments, including OTT devices and sensors. From this point onwards, we must have a RoHS certification for all devices and sensors. As of 22 July, RoHS is also a compulsory part of the CE declaration.

Without CE and RoHS, corresponding products may no longer be sold in the EU (and countries that are adapting to the EU-Directive). An exception is spare parts and parts, which are used for repair.

As a manufacturer of environmental measurement technology, we have always been committed to producing and marketing environmentally friendly products.

In order to implement the RoHS measures in our company, we have created a coordination center that has examined and, if necessary, changed all of the 30,000 articles and products.

What is RoHS?
RoHS means “Restriction of Certain Hazardous Substances” in the “Hazardous Substances Directive” in electrical and electronic equipment. This restriction is anchored in EU Directive 2011/65 / EU. If a product is RoHS-certified, this confirms that the proportion of hazardous, or difficult to dispose substances is limited to the maximum allowed. Continue reading

QUALITY ASSURANCE AND QUALITY CONTROL TECHNICAL NOTE

Download the Quality Assurance and Quality Control Technical Note Now!

The primary activities taken to assure and control data quality are aptly called quality assurance and quality control. Determining the “true value” of a water quality measurement is an important fundamental of any QA/QC program. To determine the true value, many professionals apply a second means of measuring the parameter of interest, such as another instrument that is kept serviced and calibrated just for quality control purposes or a grab sample that is evaluated using a trusted laboratory technique. Instruments such as HYDROLAB‘s produce high quality data for many applications and by leveraging the HYDROLAB Operating System you can maximize uptime with streamlined calibration tasks

Good QA/QC programs require robust calibration procedures that ultimately provide valuable information about, and confidence in, the instrument’s performance. The QA/QC Tech note highlights key information made available during a HYDROLAB multi-parameter water quality sonde calibration.

Sutron SatLink3 XMTR, a new HDR (1200 BPS) Transmitter for METEOSAT

OTT Hydromet is pleased to announce EUMETSAT – SL3-XMTR-NETDLHRDCP and SRDCP certification for the Sutron SatLink3 XMTR. METEOSAT high data rates of 1200 bps, as well as 100 bps, can now be used with the SatLink3 XMTR transmitter paired with the OTT netDL IP logger or the Wi-Fi enabled SatLink3 multi-communication logging transmitter.

Pairing the Sutron SatLink3 (SL3) XMTR Transmitter with an OTT netDL 500 / 1000 enables transmission of the OTT netDL datalogger buffer to METEOSAT. Different operating modes are available ranging from logger control of transmitter setup to scheduling the logger to send a buffer to the transmitter using RS-232. The transmitter automatically selects the proper RF output power based on antenna selection made by the user. The SL3 XMTR Transmitter supports the METEOSAT 100 and 1200 bps format and formats of other Environmental Satellites orbiting the globe,including GOES.

The SatLink3 multi-communication logging transmitter provides a cost-effective way to measure, log, calculate and transmit data from remote locations around the world. SL3 has built-in support for nearly all meteorological satellites including GOES, METEOSAT, INSAT and MTSAT for operation anywhere. Most often the SL3 is connected to sensors and transmits data on a user-set schedule, the Satlink3 has options for redundant and two-way communication using cellular and Iridium communications. Satlink3 builds upon Sutron’s 35 years’ experience providing reliable satellite communications.
