    Power-independent flow measurement with GPRS

    In a pit water purification system it was necessary to detect the discharge volumes. The operator wanted a regular and automatic transmission of readings. On the selected measurement place no mains power connection was available. Due to the risk of vandalism, it was not planned to install a switching cabinet. See the NIVUS solution for this measurement task here.

    Mercury monitoring for mercury flux measurement

    The Tekran 2537 has been used in numerous published studies to measure the deposition or evasion of mercury from natural or contaminated surfaces (i.e. flux measurements). It is anticipated that many mercury flux measurements will be needed in the future to assess the impact of climate change on mercury cycling in the environment. There are two basic ways to do mercury flux measurements. First, the dynamic flux chamber method utilizes a custom enclosure, with controlled air flow, to measure the...

  • Constant Pressure pump control valves

    For use with water well pumps and booster pumps, the Cycle Stop Valve (CSV) turns any pump into a variable flow, constant pressure system. Working in conjunction with a small pressure tank, the CSV is usually adjusted to the middle of the pressure switch range. IE; 40/60 PSI switch, 50 PSI CSV. The size of the pressure tank determines how much water can be used by the house, before the pressure drops to 40 PSI, and the pressure switch starts the pump. As long as flow rates in and around the house vary from 1 GPM...
