The K500 allows precise, metered control of water flow using an Omega brand flow meter with closed loop monitoring and adjustment.
The Em4 also comes standard with our K500 digital flow controller in addition to the standard K28 flow controller. The Em4 comes standard with 360 pounds of our color-coded by size thermoset plastic modeling media as described above. The standard static supports are engineered from high-strength aluminum and create a box slope of 3 degrees, but the vast majority of our clients opt for a single or dual-tilt base. There is a drain valve built into the upstream reservoir so the system may be quickly emptied. The two reservoirs hold a total of 70 gallons of water, so the lab should ideally have a dedicated spigot and floor drain. The scale of the Em4 allows for long-term experiments that develop mature river systems with parallel channels, multiple meanders, cut-offs, oxbows and islands, and has space for a large pool to build impressive deltas. The Em4 stream table is as much a research tool as it is a teaching tool, and can be found in laboratories at major universities around the world as well as at research institutes and museums.
The very large size of the Em4 allows a whole class of 25 plus a teacher or facilitator to participate, with a second row of 20 observers. It is also an excellent option for dedicated museum and nature center displays. This model is best suited to colleges and universities with ongoing research and teaching in river science. At 4 feet wide, it will go through standard doors only after being disassembled. The Em4 should have a dedicated teaching space or lab as it is on casters for positioning and leveling only. If you want something bigger, it will have to be custom built! This model can be crated and shipped via common carrier or shipped internationally, but we often deliver, install, and provide training in the Continental U.S.
At twelve feet long, our Emriver Em4 river model is the largest production stream table on the market.
