ORIFICE FLOWMETER

RDP-100 are ORIFICE FLOWMETER suitable for

the steam, the gas, and the liquid which arranged

an Orifice, DP Transmitter, and Indicator compactly.

This Flowmeter does not have a movable part and

it is preeminent for reliability and durability.

Since D.P. Transmitter is using the shock-proof

type by the object for high pressures, it is the safedesign which is equal also to severe use.

The measurement range can perform wide range

measurement or more in a maximum of 1:10.

When RDP-505 supply 24VDC power sources, the 4 to20mADC signal

proportional to Flow rate is outputted.

Flow rate display, Totalizing flow display, a pulse output, 4 - 20mADC output,

and the various functions method of application become possible by using

RVF-36A-1-XBXA.

In the zero point adjustment whose Flow rate uses the check and drain valve

of an output signal in zero, COM and a TEST terminal connect and use a

tester.

Since there is no Display (RVF-36A) with waterproofing structure, attachment

to the outdoors cannot be performed.

When RDP-100 supply 24VDCPower(s), 4 - 20mADC signal

proportional to diff.press. is outputted.

In the case of othersWhen there are two elbows in an entrance side: More than 18DWhen the globe valve of full admission is in an entrance side: More than 20DWhen the partition valve of full admission is in an entrance side: More than 20DAll outlet sides are required more than 6D.It is D= piping bore here.

Notes

The straight of the regular length is needed for the entrance side of Flowmeter, and an outlet side, respectively.

Straight length changes with a piping situation, existence of a valve, etc.

Keep in mind that accuracy worsens when there is no regular straight length.

Please unite the flow direction of Flowmeter, and the flow direction of fluid.

Please provide a work space for the perimeter of the place in which Flowmeter is

attached in consideration of the maintenance after attachment.

Please attach after carrying out Flushing of the piping, in case Flowmeter is at

tached after constructing new piping.

When the possibility of a freeze is in winter, please perform heat insulation disposal to Flowmeter.

Please open a valve gradually for an impact not to join Flowmeter at the time of a startup.

Removal of Flowmeter, and the notes at the time of decompositionWhen removing Flowmeter attached in piping by the bolt nut or screw connection, the pressure in piping is

perfect. Please remove after checking certainly that there is nothing and loosening a connection gradually.

While passing fluid for piping, or when pressure has joined piping, they are a bolt nut or screw connection.

Please do not remove. If it removes recklessly, there is a possibility that harm may join a human body.

Please do not perform reconstruction of Flowmeter. Please contact our company, when you check Flowmeter.

Attention of the installation direction liquid)In the case of level piping of a liquid Please attach so that

D.P.transmitter becomes a level (transverse direction).

In above or down, the case where exact measurement cannot

be performed in response to the influence of air bubbles andgarbage arises.

Attention of the installation direction steam)In the case of steamy level piping, please attach so that

D.P.transmitter becomes right under or the bottom of

slanting. When there is no space attached directly under

piping, it can install also under slanting.

Compensation Calculation For PDP-100 RDP-505 Engineering data) In case of Gas measurement Volume flow rateThe pressure change from a design condition and temperature change produces indication error.

Density change of the gas from a design condition produces a indication error.

True flow rate = Indicate flow rate Compensation coefficient

Q1 : True flow rate ( Volume flow rate m3/h(ntp) , l/h(ntp) , m3/min(ntp) , l/min(ntp) )

Q0 : Indicate flow rate ( Volume flow rate m3/h(ntp) , l/h(ntp) , m3/min(ntp) , l/min(ntp) )

: Actual Gas ( Density of an actual gas kg/m3(ntp) at 1atm , 0 )

0 : Design Gas ( Density of an design gas kg/m3 (ntp) at 1atm , 0 )

P1 : True pressure ( True operating pressure kPa(G) at gauge )

P0 : Design pressure ( Design pressure kPa(G) at gauge )

T1 : True temperature ( True operating temperature )

T0 : Design temperature ( Design temperature )
