15 sie 2019 · Besides the critical demands on sensing range of flow parameters (such as rate, velocity, direction and temperature), the properties of different target gases or liquids to be sensed pose challenges to the development of reliable, inexpensive and low powered sensors.
HyQuest Solutions’ SVS is a contact-free surface velocity sensor for open channels and rivers. The sensor uses innovative radar technology and enables reliable, non-contact measurement without the need for structural work in the water.
Easy-to-use, small, low-cost non-contact radar level & velocity sensors transmit accurate open channel water data to understand hydrologic conditions.
Based on an electrodynamic principle, Linear velocity sensors (LVS) provide a signal that is directly proportional to the vibration’s velocity amplitude. LVS are designed for low-frequency vibration monitoring and are significantly more sensitive than standard piezoelectric sensors in the low-frequency range.
1 sty 2015 · Flow velocity in microchannels can be measured by means of flow sensors. The basic principle of measuring flow velocity is by monitoring the flight time of particles or elements in the moving fluid after heat impulses are injected.
Linear velocity sensors measure the linear velocity of an object using either contact or noncontact techniques. Important performance specifications to consider when searching for linear velocity sensors include maximum velocity, maximum measurement range, accuracy, and operating temperature.
Information regarding a typical off-the-shelf ultrasonic flow sensor is provided, along with related equations for calculation of flow velocity and flow rate. Included in the appendix is a summary of standards for water meters and a list of low cost sensors suitable for this application space.
