HRM Series of FMCW method in the industry is the high level of non-contact level transmitter.
The environmental factors in non-contact level meter on the river is easy to install and high accuracy.
FMCW(Frequency Modulated Continuous Wave) Radar(Microwave Type) Level Meter send Microwave Signal that be changed periodically to the surface of the objects to be measured. Then calculate the difference in frequency of the received signal. Because the received signal is proportional to the propagation distance, it is converted into distance to water by obtaining Δf.

HM-90S Series

HM-90S Series
Model HM-90S is side mounting controls mount horizontally to any tank or vessel through a threaded or flanged pipe connection. Standard models are normally equipped with a single switch mechanism for high or low level alarm or control applications. Tandem models, when two level stage applications. Tandem models, when two switch mechanisms, are available for two level stage applications providing the operating functions of two separate instruments, such as high and low level alarm.
Side mounting units employ permanent magnetic force as the only link between the float and the switching element. As the pivoted float follows liquid level changes, it moves a magnetic sleeve into or out of the field of a switch operation. A non magnetic barrier tube effectively isolates the switch mechanism from the controlled liquid.

HM-30, HM-90 Series

HM-30, HM-90 Series
Widely applicable level switch anti-flow of various liquid tank. model HM-90/30 is designed for liquid level control based on the unique and proven princijple of a constantly engaged magnetic field.
The sensor is a weight(displacer) heavier than the liquid, when is suspended by a spring. As liquid level changes the buoyant force generated causes the spring to react (compress or expand) to weight change. When the spring react, core moves by the rod and displacement movement is reflected in magnet and fixed magnet to pivot, on or off, according to the inner rod and core position. This principle allows adjustment of the swiching point by moving the displacer along the suspension cable.
Advantages of displacer controls ard that wide switching differentials can be achieved and higher operating pressure handled where traditional float operated units could not.

HFV consists of a V-shaped cone element placed at the center of the pipe, leaving an annular space for the passage of fluid. The differential pressure generated by this device is lower than that of an orifice flowmeter with the same line size, beta ratio, and flow rate; hence, the permenent pressure loss is also lower.
Difference pressure occur between two measurement locations of the flowmeter because flow cross section that can be decribed as a restriction placed in the flow line.
We are able to know a flowrate that calculated by Bernouli’s equation from a differencial pressure.

HAPT-Series is averaging pitot tube for flow measurement. Pitot tubes are normally used to measure flow velocities at a point. However, averaging pitot tubes are advantageous in that they can measure the average flow velocity in the entire pipe line to be measured instead of obtaining the flow velocity at a point. HAPT-Series have advantages such as lower pressure loss, longer life because of no moving parts and the structure which is difficult to sediment foreign substances.
When HAPT-Series are installed in pipe channels through which fluids flow, the differential pressure is generated when a fluid passes the element between the upstream and the downstream of the element. At this time, pressure difference, ie, dynamic pressure is obtained by measuring the total pressure of upstream and static pressure of downstream. Then, the flow rates of fluid can be obtained by using relations among the dynamic pressure, flow velocity and density derived from the Bernoulli’s law.

HOP-Series is orifice plate for flow measurement. Although the orifice plates have a disadvantage of permitting a greater pressure loss than other differential pressure type flow elements like as flow nozzle, venturi tube, etc. the flow measuring using the orifice plates most popularly used because of their simpler shape, easier manufacture ability, lower cost and higher reliability.
The bore types of orifice plates include concentric, eccentric, segmental, quarter circle, square bore type and sizing calculations apply the standard codes which are ISO-5167, ASME MFC-3M etc. and Tolerance should be in full compliance with ISO & ASME Standards.
When HOP-Series is installed in pipe channels through which fluids flow, the differential pressure is generated when a fluid passes the throat of an orifice because the flow speed increases and the pressure decreases to make pressure differences between the upstream and the downstream of the throat of the orifice. Then, the flow rates of fluid can be obtained by using the Bernoulli’s law with measured differential pressure.
