Usage monitoring, such as:
• Industrial wastewater discharge monitoring
• Cooling tower deduct metering
• Heap leach mining discharge monitoring
• Well monitoring
• Turf and landscape water monitoring
• Simple as a mechanical meter
• No moving parts
• Minimal straight pipe required
• Battery powered
• Built-in rate & total indicator
• Corrosion resistant
• Pulse output ( WMP101 only)
The WMP-Series is a full-bore, plastic-bodied electromagnetic flow meter designed for flow and usage monitoring applications in 1 and 2 inch pipe. The polypropylene flow tube offers corrosion resistance to a wide range of chemicals. Its light weight and easy to install or remove from the pipe for inspection* .
With no moving parts, the magmeter permits unobstructed flow, minimizing flow disturbances and hence, straight pipe requirements. The WMP-Series can be used in piping configurations where there is little space between the meter and an elbow or valve. The WMP-Series, like other magmeters, are resistant to wear from sand and debris found in ground or surface water. Since there are no bearings or propeller to wear out , downtime and maintenance and repair costs are kept to a minimum. Because there are no mechanical parts in the flow stream, the meter tolerates high flows without damage.
The hinged, opaque polyethylene cover protects from dust and UV rays, while permitting easy access to the LCD flow rate and total display. The electronics housing is made of rugged powder-coated die-cast aluminum. It can be fitted with cross-drilled screws and seal wire for tamper-evidence. Flow rate and total can be displayed in a variety of units, customer-selected and factory-set .
The WMP-Series is used for tracking flow rate and total flow in usage monitoring applications, for instance, in compliance with regulatory requirements. These would include wells, industrial wastewater, heap leach mining discharge, cooling tower deduct metering, turf and landscape applications, and other water reclamation operations. In the event of DC power loss, or when changing the battery, the WMP is designed to retain the internal settings and flow total.
The WMP101 is externally powered via a 5-pin connector cable which also provides pulse output for use with a variety of Seametrics and other displays and controls for remote reading, data logging, pulse-to-analog conversion, and telemetry applications.
The WMP104 is a battery-operated unit for use when pulse output is not required. The standard batteries are user replaceable with an approximate 1-2 year life depending on usage. An extended battery life option offers an estimated 2-4 year life depending on usage.
EM100/ 102 series
Low Flow Magnetic Meter
* Compatible with diaphragm-type chemical metering pumps
* Chemically resistant wetted plastic parts
* Available for 1/ 4 " and 3/ 8 " pipe sizes
* Maximum flows of 4, 11, and 30 L/ min, depending on size
* Self-contained electronics
* Standard pulse and 4-20mA outputs
The EM-Series are small electromagnetic low-flow flowmeters with chemically-resistant plastic wetted parts with platinum electrodes suitable for use with a variety of chemicals. Capable of measuring pulsating flows from diaphragm-type metering pumps, they are designed primarily for electricallyconductive chemical injection applications. The 1/ 4” and 3/ 8” sizes monitor maximum flows of 1 and 3 gallons per minute ( or 4 and 11 L/ min) , respectively. Barb or NPT fittings available, and must be designated at time of order.
The EM100 and EM102 are 12-24 Vdc powered. The EM100 comes with a standard pulse output, and the EM102 with standard pulse and analog outputs. All electronics are self-contained in a single compact chemically-resistant housing, well suited for OEM applications. These meters are also appropriate for remote monitoring of chemical volume or rate using a computer or a PLC.
The EM101 is 115 Vac, 60 Hz powered and includes a rate and total display as well as a variety of outputs. For continuous transmission of a flow signal, there is a 4-20 mA output, a 0-5 volt signal, and a frequency signal proportional to flow. In addition, there are relay alarm outputs for user-set low and high flow levels.
The PE102 magmeter is designed for low-flow chemical injection or difficult-to-meter applications with pulsating metering pumps in 3/ 4” to 1/ 4” pipe/ tube. The housing is made of sturdy splashproof HDPE plastic.
With no moving parts, the PE102 can handle fluids containing particulate matter without clogging or jamming, keeping maintenance at a minimum. With no metallic parts ( 100% PVDF body and PVDF carbon fiber-filled electrodes) , the meter is corrosion-resistant and compatible with a wide range of chemicals. Accuracy is maintained with conductive fluids ( > 20 microSiemens) of varying viscosities and densities.
The PE meter is compact enough to fit most pump/ injection systems. With zero straight pipe required after an elbow, it can be easily mounted in tight spaces. The mounting bracket adds stability.
The PE meter has optocoupled current sinking or current sourcing pulse output that can be connected to the Seametrics FT420 rate/ total display or FT520 batch processor, as well as a 4-20 mA loop for powering analog devices. Outputs and power are provided through a cable with 8-pin female circular connector
This unique system of 2 " to 8 " turbine meters uses just one moving part, a precision helical rotor. Rotation of the rotor is electronically detected and processed. The high-quality jewel bearings and polished zirconia ceramic shafts minimize friction while providing long wear life in non-lubricating fluids. The entire rotor assembly can be easily removed for field service without removing the meter from the pipe.
WTP bodies are fabricated from Schedule 80 PVC fittings, WTC bodies from carbon steel tubing, and WTS bodies ( available as special order) from stainless steel tubing. The turbine insert on WTC and WTS meters is machined from a stainless steel casting. The WTP turbine insert is machined from a solid piece of PVC ( polypro in 2” size) . Turbine rotors on all models are Kynar ( PVDF) .
WT meters can be ordered with various output options. The basic model ( 100) comes with pulse output only. An electronic display ( Seametrics FT420) is mounted on the 101 model to display flow rate and total ( resettable or non-resettable) , and provide a programmable pulse or 4-20 mA output. Other electronics options include a blind 4-20 mA transmitter ( AO55) on the 102 model and a battery-powered ( FT415) rate/ totalizer plus pulse output for applications that lack power ( 104 model) . All of these controls/ displays can be mounted on the meter or remotely mounted on a wall or panel up to 2, 000 feet away. WTSeries meters are compatible for use with most other remote-mount Seametrics displays and controls as well.
