The Model ML04 Water Specialties Propeller Flow Meter™ from McCrometer is an accurate and reliable flow measurement tool in applications involving municipal ground water production wells and booster stations.
A steel flanged-end tube meter with indicator-totalizer, the Water Specialties Flow Meter is both user-friendly and highly accurate. It features measurement accuracy of ±2 percent, measures liquid flow from 40 to 60,000 GPM depending on line size and construction. The ML04 is suitable for service in line sizes from 2 to 48 inches and can be constructed for severe temperatures up to 350F.
The ML04 Propeller Flow Meter features an indicator-totalizer register that instantly delivers data on flow rate indication and totalization of flow volume. It is designed with a 4-inch display with 250-degree dial, six-digit totalizer and test sweep hand. This register can be specified for GPM, CFS, MGD or any standard unit of liquid measurement. An optional 4-20 mA and/or pulse output is available that supports SCADA systems, accommodating advanced data collection and control capabilities.
The rugged ML04 has earned a reputation for effective performance and reliability. The construction features injection molded plastic bonnets and a hinged lid with padlock hasp to prevent unauthorized entry. Fabricated steel meter tubes with straightening vanes and fabricated steel meter heads are coated inside and out with NSF approved fusion-bonded epoxy.
The ML04 and other Water Specialties propeller flow meters are constructed using advanced techniques and durable, high grade materials. Long-life ceramic dual thrust bearings handle both forward and reverse direction flow.
Versatile Water Specialties Propeller Flow Meters can be installed in vertical, horizontal or inclined positions. The Water Specialties Model ML04 Propeller Flow Meter is an ideal choice for measuring clean water flows in multiple types of municipal and industrial applications. Meter materials and performance meet or exceed AWWA standard C704-08.

PKP Process Instruments, A manufacturer and distributor of a wide range of process instrumentation introduced its model DK10 Flow Meter.
Model DK10 is a flap type flowmeter with local indication suited for flow measurement of most process fluids due to a large selection of wetted materials including aluminum, bronze, cast iron, stainless steel, PTFE and PVC. Shafts made of titanium or Hasteloy as well as plastic are available for aggressive process liquids. The unit is available with one or two alarm level outputs as well as an analog, 4-20 mA output proportional to flow.
The DK10 series flap flow meter comprises a spring-loaded flap mounted in a hemispherical chamber. The flap is deflected by the flow in the line. The deflection is directly proportional to the flow rate. The movement of the flap is transmitted via a shaft that is sealed off from the process to a mechanical pointer and the flow is displayed on a scale. One or two microswitches for flow monitoring or an analog output module can be installed in the display enclosure (optional). Each flow meter is calibrated for the liquid being monitored based on customer specifications. The devices are available with G or NPT threads for ¼” to 2″ pipes and as a wafer for mounting between two DIN or ANSI flanges on DN80 (3″) to DN200 (8″) pipe sizes.

Emerson Process Management released its Smart Meter Verification technology for Micro Motion® Coriolis flow and density meters. Smart Meter Verification delivers complete, on-line verification of device performance, saving significant expense by reducing labor and outsourced calibration service costs while eliminating process interruption.
With no need to remove the meter from the line or stop the process flow, Smart Meter Verification – at the touch of a button or on a pre-determined schedule – delivers measurement integrity feedback in under two minutes. Smart Meter Verification technology is embedded in the transmitter functionality to verify calibration and the complete health of the sensor, drive, and electronics. With no complex interpretation and no interruption to process measurement, Smart Meter Verification delivers benefits to a range of applications and industries:
o Reduces costs by minimizing manpower and services to check or calibrate meters
o Increases availability by allowing verification without process or measurement interruption
o Eliminates uncertainty by providing complete feedback whenever it is needed – with no process impact and no need for complex interpretation
o Improves safety, health and environmental impacts by reducing trips to the field and the need to break process seals.
o Checks the entire flow measurement meter – sensor and electronics – for complete measurement certainty
o Is easy to operate at the touch of a button, on a pre-determined verification schedule, or automatically based on process events
Micro Motion Coriolis flowmeters lead the industry in measurement performance and reliability, and are part of Emerson’s broad range of intelligent, digital field devices that power the PlantWeb(TM) digital plant architecture. Further cost savings, increased plant availability, and enhanced safety and environmental compliance are achieved when the flowmeters are integrated into the PlantWeb digital plant architecture.
Turbine Meter Provides Leak Detection

Flow Technology today announced the FT-LD (Leakage Detection) turbine flow meter system. This advanced solution offers significant improvements in flow measurement accuracy under dynamic temperature conditions. The FT-LD system provides inferred mass measurements for leakage detection by correcting for temperature effects on fluid volume.
Today’s industrial companies must ensure the ruggedness and reliability of every component used in their products. For example, manufacturers of off-road equipment employ automated test stands to test torque converters for leakage prior to assembly in tractors, bulldozer, backhoes, etc. Transmission oil is measured before entering the torque converter and again after exiting. Any difference in the flow rate can be attributed to leakage in the device. This testing is complicated by the fact that fluid volume at cool temperature is not the same as at high temperatures.
The FT-LD Turbine Meter Leak Dectector
Employing Flow Technology’s FT Series turbine flowmeter paired with the LinearLink(TM) Temperature Compensated Interface (TCI), the FT-LD system helps users obtain precise leakage measurements for fluids such as engine oil, transmission oil and hydraulic fluid. The FT Series meter is an ideal choice when high accuracy, compact size and fast response are critical. The LinearLink TCI is a sophisticated electronics platform for flow meter linearization, viscosity correction and density compensation.
For leakage measurement, FT Series turbine flow meters are installed in series on a test stand fixture with the inlet meter located downstream of the device-under-test (DUT) and the outlet meter positioned upstream of the device. The system is then pressurized with the application fluid and the DUT is run through pre-programmed tests to evaluate its overall performance.
The LinearLink TCI infers mass by density compensation, essentially bringing the cold and hot fluid volumes to a standard. Regardless of the fluid temperature, the compensated volume of flow is converted to a weight equivalent-allowing the user to determine the amount of leakage that has occurred during a test procedure. Fluid leakage rates are calculated by subtracting the outlet mass flow rate from the inlet mass flow rate.
