The ALMAGWP Series from SmartMeasurement is a family of versatile, low-cost electromagnetic flowmeters ideal for measuring the flow rates of conductive liquids. The ALMAGWP is offered in sizes ranging from ⅜" through 80" with ANSI and DIN type flange connections or wafer-type connections. A wide array of standard & optional features are available, including local or remote display types, a variety of outputs such as analog 4-20 mA, pulse, RS-232C, and HART, IP68/NEMA 6 protection, low power consumtion, and several available liner and elctrode materials.
The ALSONIC-FDSP series is a fixed-mount, transit-time ultrasonic flowmeter with clamp-on transducers for non-invasive liquid flow rate measurement. Our Alsonic-DSP uses patented "fine time measurement technology" where the meter's ultrasonic beams are capable of measuring the fluid velocity at pico-seconds time intervals. This rapid succession of velocity measurements enables accurate, drift-free flow measurement of ultraclean to dirty liquids containing up 30% of solids or gas bubbles. The use of DSP technology enables "Cross Correlation" of ideal signals to cancel extraneous noise and create a three-dimensional cross section of the flow velocity distribution profile of the medium flowing through the pipe.
The ALSONIC-HL series is a low cost, portable hand held ultrasonic flowmeter with clamp-on transducers for non-invasive liquid flow rate measurement. The ALSONIC-HL makes use of the proven transit-time ultrasonic measuring technique, which provides excellent accuracy while allowing for easy set-up and installation.
Alsonic Building Automation - Energy meters employ transit-time ultrasonic flow Measuring technology combined with two integrated PT1000 RTD temperature sensors for calculating both total and instantaneous energy consumption. These in-line ultrasonic flow meters are available for line sizes ranging from ½" to 4" (15-100mm). The Alsonic BA Energy meter may be used to provide highly accurate thermal energy measurement in chilled water, hot water and condenser water systems. Our battery powered, microprocessor-based field programmable electronics provide local indication of energy, flow and temperature data via an alphanumeric LCD display. An isolated solid state dry contact is provided for indication of pre-programmed totals or alarm conditions. Optional analog outputs and RS485, M-bus as well as other network communications are also available.
SmartMeasurement’s ALCM coriolis mass flowmeters use two tubes in a parallel arrangement which are rotated at their resonant frequency by coils. Any mass flow passsing through the tubes will generate coriolis forces which appear whenever a mass moves radially in a rotating system. The forces have opposite effects on the inlet and outlet side, deforming each pipe by a minor amount. The excursion of the pipes is detected by the inlet and outlet-side sensors. The phase shift between the rotational frequencies of both pipes is directly proportional to the mass flow rate and the resonant frequency of both pipes changes in accordance with the density of the fluid media. This effect allows for measurement of the density. Using only one sensor, both density and temperature measurements may be performed. The extent of deformation of the pipes is temperature-dependent. Therefore, the temperature is measured for compensation purposes. Using only one primary sensor, values including mass flow, density, and temperature may be measured. The ALCM's microprocessor-based circuitry allows for conversions such as volumetric flow and % concentration to be calculated.
Vortex flow sensing technology relies on measuring the number of vortex pulses generated by a bluff body immersed in the flow stream. The SMC ALVT Vortex flow meter uses dual sensor technology, producing two independent vortex signals which allows for signal amplification and common mode noise reduction. Our sensors never touch the process fluid; the crystal sensors are bonded behind a stainless steel wall. The electronics pick up the slightest pressure pulsations generated by the vortices through the stainless steel wall. This design allows meters to have an extremely wide turndown while maintaining an almost unlimited upper end and a high pressure rating.
