DHI’s Engineering provides detailed studies on the terrain and geography of the job to be deployed. The software supplied by DHI can determine the hydraulics and pressures a specific rig up will en-counter at the varying flow rates. This allows engineers to deter-mine how much pump horse power and throughput capacity is needed and where to put these pumps for optimum performance, economy and versatility.

The iMAG-Series is the most economical flanged electromagnetic flowmeter on the market. With electrodes designed to discourage fouling, it is available in 3” to 12” pipe in municipal or industrial water, waste and reclaimed water, pump stations, and packaged plant applications. Minimal straight pipe requirements allow iMAG-Series meters to be used in piping configura-tions where there is little space between the meter and an elbow.
iMAG-Series meters are CE certified, certified to NSF/ANSI standard 61 and are rated IP68 for applications where the meter may be operated under water to a depth of at least 10 feet (3 meters) continuously.
Max Flow Rate for 12” Meter 11,565 GPM | 8” Meter is 5140 GPM minimum rate for 8” is 750 GPM

DHI uses top quality Hammerhead hose made in the EU, built to last and minimize failers.

Poor Quality Hose Issues:

Elongation: occurs when the inner fabric (jacket) is not woven optimally to minimize
elongation. A properly woven hose jacket should elongate no more than 2%. Cheap
hoses often elongate by as much as 12% at working pressure; this causes severe snaking.
Snaking across an abrasive surface can tear the outer coating. Severe snaking can push
hose onto a road or to roll down a hill. Elongation is relaxed after pressure is released.

Expansion: all lay flat hose will expand some when the hose is pressured up. Extreme
expansion occurs when inner fabric is not woven optimally. The fabric weave is what
gives the hose it’s strength and it is also what prevents the hose from elongating and
expanding. Too much hose expansion makes it hard to pig a line effectively and it also
puts too much stress on the hose where they meet couplings, which can damage the hose.

Burst at low pressures: There are no standards for lay flat hose larger than 6” diameter.
It is common for manufacturers to claim working pressures of 200 psi even if their burst
pressures are not much higher than the claimed working pressure. Pressure testing has
proven several manufacturers hose to burst with too little margin for safety.
