SLH-P Series Portable Ultrasonic Flow Meter

SLH-P Series Portable Ultrasonic Flow Meter

SLH-P Portable ultrasonic flow meter realizes the noncontact measurement. It is ideal for flow surveys and closed pipe .it is used where non-invasive measurement of liquids is required. Built-in SD card and printer can timely or regularly print pre-set measuring results.

Temperature and heat can also be measured by connecting clamp on temperature transducer. Widely be used in water supply, heat supply, chemical industry, and machinery and energy resources.
Silver Automation Instruments as a China supplier for portable ultrasonic flow meters, We do not supply best price instruments; also provide reliable quality flow meters.
