Virtual Hydromet Salempur, Roorkee, Uttarakhand

With this full-electronic counter it is possible to receive frequencies for all flow velocities. The impulses generated by the current meter are added and indicated in relation to the preselected time. The timing starts from the first impulse. With the basic version, the impulses can be counted in freely pre-definable measurement intervals. Optionally, the impulse number to be counted can be pre-selected (Z6-I). A further option is the direct calculation of the current velocity by means of pre-definable equations (Z6-V). There are several memory locations for all adjustments. All the user-defined adjustments can be made directly at the device or via connected PC and can be saved permanently

The DischargeApp is a low-cost, user-friendly smartphone application which provides fast and accurate discharge measurements in rivers and open channels. It is only needed to have four ground control points on the field, no expensive equipment is left at the place. Additionally, the cross-section of the water body needs to be measured. Depending on the size and complexity of the channel, the initial site setup may take between 15 minutes and 1 hour, but his has to be done only once. Measuring the discharge on a dedicated DischargeApp site takes less than a minute. The computation occurs locally on the smartphone, hence the DischargeApp can be used to measure in regions without network coverage. Once the measurement is done, data transmission to the cloud is possible immediately or later, as soon as internet is available. This allows error-free data transmission and storage. The measurements can be accessed via the integrated DischargeDataHub platform. On this platform measurement data, sites, users and user permissions can be managed. Access to the data is secure and login protected
