Turkish company request: test equipment

As an engineering company, **********, we are creating a test rig in order to perform performance tests of a positive displacement rotary pump within the scope of a project we are producing.
In this context, we need measuring equipment suitable for DN50 or DN60 piping and that can operate reliably under the following operating conditions:
Pressure range: 0–25 bar
Temperature range: 0–150°C
Flow rate: Maximum 257 L/h
We would like to receive technical support in determining the appropriate equipment we need and, if possible, your product/price offers.
