SRX Pulse Counter With Fittings

TR-77802 SRX Pulse Counter - fittings kit included | DGSI Slope Indicator Submersible Pumps

Used to determine the total flow of the SRX pump.

• The compact and robust counter is installed in the air supply line at the well head.
• As the pump cycles, the counter senses the drop in air pressure that indicates the pump has cycled.
• The number of cycles is multiplied by the internal volume of the specific pump you are using to calculate the flow rate. The counter body can be disassembled for cleaning.
• Available without fittings kit (TR-77802)

Pulse Counter Specifications

• Materials: Delrin body and piston, 304 stainless steel spring, Nylon set screw, plated steel end fittings, Neodymium iron magnets (2) and polycarbonate counter
• Dimensions: 1.5 in dia. x 4.75 in
• Compatible with SRX LP and most other pumps and applications.

SRX Pumps:

• The SRX is an air-powered pump used to extract ground water or total fluids at variable rates equal to the well recharge rates.
• The SRX is available in a 1.75in OD or 3.5in OD for use in 2” and 4” wells.
• Pump flow rates are up to 9.5 gpm.
• The SRX pump is available in top loading for recovering total fluids or bottom loading for dissolved phase and higher pumping rates.
• Top-loading pumps (SRX-R TL) are selected for pumping total fluids (LNAPL and ground water simultaneously). Water table drawdown will be maintained at a level corresponding to the top inlet of the pump. Pumps of shorter lengths are available for lower drawdown requirements
• Bottom-loading pumps (SRX-R BL) are selected for dissolved phase or DNAPL applications. When installing the pump, the head is positioned at a depth of approximately 10 inches higher than the desired water table depression.

1 SRX-R TS = top-loading, short, SRX-R BL = bottom-loading, SRX-R TL = top-loading.
2 Volume (US gal) per pump cycle will vary slightly depending on air pressure supplied to pump, depth of well, etc.
3 Maximum flow rates can vary due to air pressure supplied to pump, depth of well, etc. For assistance, contact DGSI.
* SRX-R inlet filter only.
