Hydro Air Process Instruments products

Hydro Air DO sensor is membrane based and uses polarographic technology to determine dissolved oxygen levels. The sensor is comprised of double-electrode cell, with a cathode and an anode, joined by the electrolyte and separated from the sample by a permeable membrane. The sensor generates a potential, mV, related to the dissolved oxygen in contact with membrane. It provides low cost solution for the dissolved oxygen measurement typically in the aeration tank and in the aquaculture ponds.

Hydro-Air RDS series radar level meter has 6 different series (91, 92, 93, 94, 95 & 96) for various measuring ranges and different kinds of antennas. It is a compact series level transmitter for non-contact continuous level measurement of liquids and solids. In radar level measurement, microwaves are transmitted by the antenna system of the radar sensor to the measured product, reflected by the product surface, and received back by the antenna system. The time from emission to reception of the signals is proportional to the level in the vessel. RDS series has different types of antennas including cone type, anti-corrosion type, water droplet antenna, and conical plastic type for various types of applications.

PTS81 Monocrystalline Silicon Differential Pressure Transmitter has leading accuracy and stability due to adoption of Germany advanced MEMS technology for the sensor monocrystalline twin beams suspension design. The built-in professional signal processing module can perfectly combine the static pressure compensation and temperature compensation under the wide range of static pressure and temperature change. This will provide high measuring accuracy and long-term stability. It has great flexibility with multiple display units (mA, Pa, KPa, MPa, bar, mbar, %, psi & mmH20). Besides, it has built-in 3 buttons with quick operation and field adjustment functions.

Hydro-Air FS Series electromagnetic flowmeter are intended for fluid measurement in most industries including water, wastewater, chemical, etc. There are two basic components of electromagnetic flowmeter. The detector includes flow tube, isolating liner and measuring electrodes and the convertor responsible for signal processing, flow calculation, display and output signals. The materials of construction of the wetted parts (liner and electrodes) should be appropriate for the type of applications. All the electromagnetic flowmeters are factory tested and calibrated. A calibration certificate is included for each of the flowmeter.
