Based on the long experienced know-how on the TOKYO KEISO's thermal flowmeters, SRT1000 series has enhanced its performance such as a reading accuracy, a reliable sealing by metal and a digital output. In measuring various gases it covers wider sizes ranging from 10 mm to even 1500 mm as standard.
Either the integral type with the sensor integrated with an indicator and converter or the separate type with an indicator and converter remotely mounted is available for the application.
Various outputs are available for your convenience such as pulse, high and low alarms, and digital output via RS485, as well as 4 to 20 mADC, 0 to 5, 0 to 10 VDC analog outputs all in standard features.
The SRT1000 covers much wider measuring range than the current thermal flowmeters.
Accurate flow measurement as high as ±1% R.D. between 10 to 100% F.S. and ±0.5% R.D. in less than 10% F.S. thanks to the unique calibration facilities.
The sensor has a metallic sealing mechanism, durable and corrosion resistant.
Negligible small pressure loss by a simple sensor made of stainless steel placed in the flow path.
Not more than 1 second at 63% response.
The sensor consists of a heated sensor and a temperature sensor which allows also temperature indication in the piping.
Flow rate compensation by inputting 4 to 20 mADC pressure signal for unstable process.
Normal flow rate at 0°C and 1 atm, standard flow rate, actual flow rate or mass flow rate is available.
